A 50 kg object strikes the unstretched spring to a vertical wall having a spring constant of 20 kN/m. Find the maximum deflection of the spring. The velocity of the object before it strikes the spring is 40 m/s.

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

What will be the impact on the velocity of an object if it falls with constant acceleration?

What will be the amount of net force when an object is falling down with constant velocity?
