Change in momentum of the ball is 74.8 kg m/s
change in velocity of the ball is 0.25 m/s
What is change in momentum?
Change in momentum is the product of mass and change in velocity this is also equal to impusle which ia a product of force and time.
Change in momentum = m ( v - u ) = Impulse = f * t
m = mass
change in velocity = v - u
v = final velocity
u = initial velocity
f = force
t = time
Given:
f = 187 N
m = 7.3 kg
t = 0.40 s
!.
Change in momentum = impulse = f * t
Change in momentum = 187 * 0.40
Change in momentum = 74.8 kg m/s
2.
Change in momentum = m * ( v - u )
( v - u ) = change in momentum / m
( v - u ) = 187 / 7.3
( v - u ) = 10.25 m/s
