A 0.45 kg football traveling at a speed of 22 m/s is caught by a stationary receiver. If the football comes to a rest in the receiver's arms, the magnitude of the impulse imparted to the receiver by the ball is

0.9Ns

Explanation:

Impulse formula is expressed as;

Impulse = Ft = m(v-u)

Impulse = m(v-u)

m is the mass of football = 0.45kg

v is the final velocity = 22m/s

u is the initial velocity = 0m/s

Impulse = 0.45(22-0)

Impulse = 0.45 * 22

Impulse =  0.9Ns

Hence the magnitude of the impulse imparted to the receiver by the ball is 0.9Ns

the answer is 3.1 his answer is wrong mines is right
