No, momentum is conserved so:
momentum before=momentum after
it is C. 100 kg m/s
4. hyperdermis is not a layer of skin
Answer:
14 m/s
Explanation:
The motion of the book is a free fall motion, so it is an uniformly accelerated motion with constant acceleration g=9.8 m/s^2 towards the ground. Therefore we can find the final velocity by using the equation:

where
u = 0 is the initial speed
g = 9.8 m/s^2 is the acceleration
d = 10.0 m is the distance covered by the book
Substituting data, we find

The ground exerts an equal force on the golf ball.
The SI unit for acceleration is m/s2 ( D)
