Physics

An 80- quarterback jumps straight up in the air right before throwing a 0.43- football horizontally at 15 . How fast will he be moving backward just after releasing the ball? Suppose that the quarterback takes 0.30 to return to the ground after throwing the ball. How far d will he move horizontally, assuming his speed is constant?

  2. I think just giving the person an answer is a little unhelpful.

    m(Vf-Vi)=m(Vf-Vi)
    80(Vf-0)=0.43(15-0)
    80(Vf)=0.43(15)
    80(Vf)=6.45
    Vf=0.80625 m/s

    0.080625 m/s * 0.03 m = 0.0241875 m the QB moves horizontally.
