Answer:
The magnitude of change in the ball's momentum is 4 kgm/s
Explanation:
Given;
mass of the ball, m = 0.2 kg
initial velocity of the ball, u = 40 m/s
final velocity experienced by the ball, v = 60 m/s
Therefore, the change in momentum of the ball is given as final momentum minus initial mometum;
ΔP = mv - mu
ΔP = m(v-u)
ΔP = 0.2 (60 - 40)
ΔP = 4 kgm/s
Therefore, the magnitude of change in the ball's momentum is 4 kgm/s
Answer:
84%
Explanation:
g = Acceleration due to gravity = 9.81 m/s²

x = 10 m
t = Time taken
= 3.5 m/s (assumed, as it is not given)

We have the equation


From continuity equation we have

Fraction is given by

The fraction is 84%
