Question 1

A particle is moving with a uniform speed v in a circular path of radius r with the centre at O. When the particle moves from a point P to Q on the circle such that POQ = θ, then the magnitude of the change is velocity is

Question 2

The velocity of a car travelling on a straight road is 36 km h–1 at an instant of time. Now traveling with uniform acceleration for 10s, the velocity becomes exactly double. If the wheel radius of the car in is 25 cm, then when of the following numbers is the closest to the number of revolutions that the wheel makes during this 10 s?

Question 3

In the figure as shown, the pulley is light and massless thread is having two masses m1 and m3 at their ends. Then the acceleration of center of mass of two blocks is (Assuming m3 > m1)

All the graphs below are intended to represent the same motion. One of them does it incorrectly. Pick it up.

Question 5

A drunkard walking in a narrow lane takes 5 steps forward and 3 steps backward, followed again by 5 steps forward and 3 steps backward, and so on. Each step is 1 m long and required 1 second to cover. How long the drunkard takes to fall in a pit 13 m away from the start?

Question 6

A person standing on the floor of an elevator drops a coin. The coin reaches the floor of the elevator in a time t1 if the elevator is stationary and in time t2 if it is moving with constant velocity. Then -
