In the climax of a movie, the hero jumps from a helicopter and the villain chasing the hero also jumps from the same level . After sometime when they come at same horizontal level, the villain fires bullet horizontally towards the hero, Both were falling with constant acceleration `2(m)/(s^2), because of parachute, Assuming the hero to be within the range of bullet, which of the following is correct.

A

bullet will hit the hero

B

bullet will pass above the hero

C

bullet will pass below the hero

D

bullet will definitely hit the hero, if both were falling with constant acceleration `g` instead of `2(m)/(s^2)`

The correct Answer is:
To solve the problem, we need to analyze the motion of both the hero and the villain, as well as the bullet fired by the villain. ### Step-by-Step Solution: 1. **Understanding the Scenario**: - Both the hero and the villain jump from the same height and fall under the influence of gravity with a downward acceleration of \(2 \, \text{m/s}^2\) due to their parachutes. - The villain fires a bullet horizontally when he reaches the same horizontal level as the hero. 2. **Vertical Motion of the Hero and Villain**: - The vertical motion of both the hero and the villain can be described by the equation of motion: \[ h = \frac{1}{2} a t^2 \] where \(h\) is the distance fallen, \(a = 2 \, \text{m/s}^2\), and \(t\) is the time of fall. 3. **Vertical Motion of the Bullet**: - The bullet, once fired, will also experience a downward acceleration due to gravity, which is approximately \(9.8 \, \text{m/s}^2\). - The vertical motion of the bullet can also be described by the same equation of motion: \[ h_b = \frac{1}{2} g t_b^2 \] where \(g \approx 9.8 \, \text{m/s}^2\) and \(t_b\) is the time taken for the bullet to fall. 4. **Comparing the Vertical Distances**: - At the moment the villain fires the bullet, both the hero and the villain have fallen the same vertical distance \(h\) after time \(t\). - The bullet will start falling from the same height as the hero but will accelerate downwards faster due to the greater gravitational acceleration. 5. **Conclusion**: - Since the bullet falls faster than the hero (because \(9.8 \, \text{m/s}^2 > 2 \, \text{m/s}^2\)), it will pass below the hero as both continue to fall. - Therefore, the correct answer is that the bullet will pass below the hero. ### Final Answer: The bullet will pass below the hero.

A boy and a block, both of same mass, are suspended at the same horizontal level, from each end of a light string that moves over a frictionless pulley as shown. The boy start moving upward with an acceleration 2.5m//s^(2) relative the rope. If the block is to travel a total distance 10m before reaching at the pulley, the time taken by the block in doing so is equal to:

Two particles, one of mass m and the other of mass 2m, are projected horizontally towards each other from the same level above the ground with velocities 10 m/s and 5 m/s, respectively. They collide in air and stick to each other. The distance of the combined mass from point A is

A mass M=1 kg lies on a smooth horizontal base of a rough inclined plane at an angle 37^(@) with the horizontal as shown in figure-4.81. A bullet of mass m=0.1 kg is fired horizontally with a velocity u=110 m//s and gets embeded in it almost immediately. The impluse imparted carries the combined mass up the incline and finally lands on the horizontal level with the horizontal base. If the length of the incline is I=1.8 m and the incline offers a coefficient of kinetic friction 0.5 to the sliding of the mass, find the horizontal distance from the base of the incline to the point of landing of the combined mass. Assume the contact of the incline with the horizontal plane is smooth and mass is not jerked when starts up on incline plane.

A man is standing on a road and observes that rain is failing at angle 45^(@) with the vertical. The man starts running on the road with constant acceleration 0.5m//s^(2) . After a certain time from the start of the motion, it appears to him that rain is still falling at angle 45^(@) with the vertical, with speed 2sqrt(2)m//s . Motion of the man is in the same vertical plane in which the rain is falling. Then which of the following staement(s) are true.

Two persons, A of mass 60 kg and B of mass 40 kg , are standing on a horizontal platform of mass 50 kg . The platform is supported on wheels on a horizontal frictionless surface and is initially at rest. Consider the following situations. (i) Both A and B jump from the platform simultaneously and in the same horizontal direction. (ii) A jumps first in a horizontal direction and after a few seconds B also jumps in the same direction. In both the situations above, just after the jump, the person ( A or B ) moves away from the platform with a speed of 3 m//s relative to the platform and along the horizontal. Final speed of the platform in situation (i), i.e., just after both A and B have jumped will be a.
