A ball thrown by one player reaches the other in 2 sec. The maximum height attained by the ball above the point of projection will be about:
Correct answer: C. 5 m
- A. 10 m
- B. 7.5 m
- C. 5 m
- D. 2.5 m
Explanation
The maximum height of the projectile can be determined by analyzing the vertical motion. In this case, since the time taken to reach the other player is 2 seconds, the time to reach the maximum height would be half of this, which is 1 second. Using the formula for maximum height and substituting the given values, the correct answer is 5m. The other options are incorrect because they do not apply the correct formula or consider the given information accurately.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.

Two balls are projected from the top of a tower of height 120 m, one with an initial upward velocity of 36 km/h and the other with an initial downward velocity of 36 km/h. The speed of each ball just before hitting the ground is: (take g = 10 m/s2 )
Two bodies are projected with the same velocity. If one is projected at an angle of 30o and the other at an angle of 60o to the horizontal, the ratio of the maximum heights reached is:
One fielder throws a ball and in 4 seconds it reaches to another player. So, the maximum height reached by the ball above the point of projection would be about:
A projectile is fired at 30o with momentum p. Neglecting friction, the change in kinetic energy when it returns to the ground will be:
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:
Can an object maintain uniform velocity when its acceleration is not zero?
