A 200 N weight falls from rest at height “h” and strikes spring having a spring constant of 10 N/mm. the maximum compression of spring is 100 mm, after the weight the weight strikes the spring. Compute the value of h is meter.

What is the value of the velocity of a football when it attains its maximum height?

The 7 m long beam, supported by a cable and resting on a smooth inclined surface at point A, is subjected to 
a 150 KN point load. Determine the position ‘x’ of the point load to maintain equilibrium. Neglect the weight of 
the beam. 

Identify two true statements about projectiles among the following

1. The horizontal component of velocity always remains constant during projectile

2. The vertical component of velocity remains constant during projectile

3. The vertical component of velocity changes due to the downward gravity

4. The kinetic energy becomes zero at maximum height
