A passenger is walking on a walkalator (horizontal escalator) at a speed of 6 km/hr relative to the escalator. He starts from point P on the ground and reaches point Q on the ground. The walkalator is moving at 3 km/hr relative to the ground in the direction of point Q. The distance PQ is 120 m. The time taken by him to reach point Q is:

A cricketer throws a ball up to a horizontal distance of 150 meters. If he throws the ball vertically upwards with the same effort then, what will be the maximum height projected by the ball?

Two guns on a battleship simultaneously fire two shells at the same speed at enemy ships. If the shells follow the parabolic trajectories as shown, which ship will get hit first?

A particle is moving along a circular path of radius 2 m and with a uniform speed of 5 ms–1. What will be the change in velocity when the particle completes half of the revolution?

The oscillating object overshoots the rest position due to:

If we are standing in a bus and the driver applies a brake then we feel:

If displacement = 15 m and time t = 10 seconds, then average velocity is:
