An athlete is throwing a discus in a sports event. He holds the discus in his hand and gives it a circular motion by rotating his own body. Then he releases the discus in the desired direction. The discus moves along a straight line.
Which statement about the direction of the velocity of this discus is correct?

A

the direction of velocity constantly changes

B

the direction of velocity is constant through out the motion

C

direction of velocity changes at some points only.

D

both (b) and (d) are correct.

Text Solution

Verified by Experts

The correct Answer is:
A
In case of circular motion, the direction of velocity of the object changes constantly.

A mass M hangs on a massless rod of length l which rotates at a constant angular frequency. The mass M moves with steady speed in a circuilar path of constant radius. Assume that the system is in steady circular motion with constant angular velocity omega . The angular momentum of M about point A is L_(A) , which lies in the positive z direction and the angular momentum of M about point B is L_(B) . The correct statement for this system is :

A man of mass 80 kg is riding on a small cart of mass 40 kg which is rolling along a level floor at a speed 2 m/s . He is running on the cart , so that his velocity relative to the cart is 3 m/s in the direction opposite to the motion of cart . What is the speed of the centre of the mass of the system ?

    Benny is a student of class IX in a city school but his brother John studies in class V. One day John was playing with his friends just outside the house. John had a ballon in his hands. John inflated the ballon by filling air into it. He did not tie the mouth of this air-filled ballon with a thread. John just held the mouth of the inflated ballon tightly in the downward direction (towards the ground) and released it. When the inflated ballon (containing compressed air) was released with its mouth in the downward direction, then the ballon moved upwards on its own. Benny was observing this incident vert carefully. The upward going ballon reminded Benny of the principle of working of an important device. Benny also explained everything to his younger brother. Name the device whose principle of working is demonstrated by the inflated ballon released by John? (b) Name and state the principle (or law) on which the above device works. (c) Explain and working of this device briefly. (d) Which of the Newton's laws can also be said to be involved in the working of the above device? (e) Name another device which also works on the same principle as this device. (f) What values are displayed by Benny in this episode?

    An athlete throws a discus from rest to afinal angular velocity of 15 rad s^-1 in 0.270 s before releasing it. During acceleration, discuss moves a circular arc of radius 0.810 m . Acceleration of discus before it is released is.

    Assertion: When a person walks on a rough surface, the frictional force exerted by the surface on the person is opposite to the direction of tendenc of motion his leg. Reason: If a body moves with constant velocity, then it means that body is moving along straight line & there is no acceleration.
