An 80-kg quarterback jumps straight up in the air right before throwing a 0.43-kg football horizontally at 15 m/s . suppose that the quarterback takes 0.30 s to return to the ground after throwing the ball. how far d will he move horizontally, assuming his speed is constant?

0.0241875 m

Explanation:

= Mass of quarterback = 80 kg

= Mass of football = 0.43 kg

= Velocity of quarterback

= Velocity of football = 15 m/s

Time taken = 0.3 seconds

In this system as the linear momentum is conserved

Assuming this velocity is constant

The distance the quarterback will move in the horizontal direction is 0.0241875 m

good for her? ? where is the question?
