Object orbiting the earth at a height above the ground

Reference no: EM13660766

1) What is the escape velocity (in m/s) for an object orbiting the Earth at a height above the ground of 6.9E6 m?

2) A pitcher throws a 0.145-kg baseball to a batter at 36 m/s. The batter hits the ball straight back at the pitcher at 49 m/s. The amount of time that the bat and ball are in contact is 9.0E-3s. What is the force (in N, assumed to be constant) among the ball and bat?
