Answer:
8.0 Ns
Explanation:
Change in momentum is given as:
Final momentum - Initial momentum
= m*v - m*u
Where m = mass of ball
v = final velocity
u = initial velocity
Change in momentum = (2.0 * 3.0) - (2.0 * 7.0)
= 6.0 - 14.0 = -8.0 Ns
The magnitude will be |-8.0| = 8.0 Ns
The metric unit is the Newton (N), or the
