A railroad car is moving in the +x direction on a straight and level track A person in the railroad car throws a ball the ball follows trajectory shown relative to the railroad car from an inspection of the trajectory what can be concluded about the motion of railroad car ? Treaty axis along vertical

A

it is moving at a constant speed

B

it is speeding up

C

it is slowing down

D

none of the above can be concluded

Text Solution

Verified by Experts

The correct Answer is:
C
if railroad car is slowing down then (it is retarding) car will be non-inertial frame and apply pscudo in forward direction So in car frame particle will accelerate horizontally

Two persons A and B travelling at 60 km//hr^(–1) in their cars moving in opposite directions on a straight road observe an airplane. To the person A, the airplane appears to be moving perpendicular to the road while to the observe B the plane appears to cross the road making an angle of 45° . (a) At what angle does the plane actually cross the road (relative to the ground). (b) Find the speed of the plane relative to the ground.

A boy is standing on a flatcar that is moving with uniform acceleration on a level track. At the instant when flatcar is moving with velocity 10 m/s due east the boy throws a ball with velocity 20 m/s in direction 45° above the east with respect to the flatcar in plane of motion of flatcar. What should be the acceleration of the flatcar so that the boy can catch the ball without moving anywhere on the flatcar? Assume acceleration due to gravity 10 m/ s^(2) .

A cart is moving along +x direction with a velocityof 4 m//s . A person on the cart throws a stone with a velocity of 6 m//s relative to himself. In the frame of reference of the cart the stone is thrown in y-z plane making an angle of 30^@ with vertical z-axis. At the highest point of its trajectory, the stone hits an object of equal mass hung vertically from the branch of a tree by means of a string of length L. A completely inelastic collision occurs, in which the stone gets embedded in the object. Determine : (i) The speed of the combined mass immediately after the collision with respect to an observer on the ground, (ii) The length L of the string such that the tension in the string becomes zero when the string becomes horizontal during the subsequent motion of the combined mass.

A railroad flatcar of mass M can roll without friction along a straight horizontal track. Initially, a man of mass 'm' is standing on the car, which is at rest. What is the velocity of the car if man runs to the left so that his speed relative to the car is v_(rel) .
