Question

In a football game, a receiver is standing still, having just caught a pass. Before he can

inge
move, a tackler, running at a velocity of +4.5 m/s, grabs him. The tackler holds onto the
receiver, and the two move off together with a velocity of +2.6 m/s. The mass of the
tackler is 115 kg. Assuming that momentum is conserved, find the mass of the receiver.

Answer 1

a receiver in a football game is standing still, having just caught a pass. before he can move, a tackler, running at a velocity of 4.4 m/s, grabs him. the tackler holds onto the receiver, and the two move off together with a velocity of 3 m/s. the mass of the tackler is 120 kg. assuming that momentum is conserved, find the mass of the receiver.

Step-by-step explanation:

but 4.4m first then 3m next 120
