Explanation:

Given:

(A)

height between John and William,

Using the equation of motion:

where:

v_J = final velocity of John at the end of the slide

u_J = initial velocity of John at the top of the slide = 0

Now putting respective :

Now using the law of conservation of momentum at the bottom of the slide:

Sum of initial momentum of kids before & after collision must be equal.

where: v = velocity with which they move together after collision

is the velocity with which they leave the slide.

(B)

Now we find the force along the slide due to the body weight:

Hence the net force along the slide:

Now the acceleration of John:

Now the new velocity:

Hence the new velocity is slower by
