A0.45-kilogram football traveling at a speed of 22 meters per second is caught by an 84-kilogram stationary receiver. if the football comes to rest in the receiver's arms, the magnitude of the impulse imparted to the receiver by the ball is

The magnitude of the impulse imparted to the receiver by the ball is  –9.9 Kg•m/s

From the question given above, the following data were obtained:

Mass of ball (m) = 0.45 Kg

Initial velocity (u) = 22 m/s

Final velocity (v) = 0 m/s

The magnitude of the impulse imparted to the receiver by the ball can be obtained as follow:

Impulse = Change in momentum

I = m(v – u)

I = 0.45 (0 – 22)

I = 0.45 (–22)

Thus, we can conclude that the magnitude of the impulse imparted to the receiver by the ball is  –9.9 Kg•m/s
