Question

Suppose that you hit a tennis ball with an initial speed of 15.4 m/s, at an angle of 48.7

Answer 1

Answer #1

h=vo*t*sin(48.7)-0.5gt^2

2.1 = 11.57t - 4.9t^2

t1 = 2.16

t2 = 0.198

so

d=vo*cos(48.7)*2.16 = 21.95

21.95 - 10 = 11.95

2.16- 0.25 = 1.91

v = d/t = 11.95/1,91 = 6.26 m/s

Suppose that you loft the ball with an initial speed of v = 15.2 m/s, at an angle of θ = 49.2° above the horizontal. At this instant your opponent is d = 10.0 m away from the ball. He begins moving away from you 0.250 s later, hoping to reach the ball and hit it back at the moment that it is h = 2.09 m above its launch point. With what minimum average speed must he move?

a tennis ball was hit with a tennis racquet. The ball was hit in the same direction from which it approached the raquet ( the opposite of the direction it was going), so it was s essentially a one- dimensional collision. The 60.0 gram tennis ball approached the racquet with a speed of 34.3 m/s. The tennis racquet gave the ball an impulse of 4.5 newton-seconds. a) Find the velocity of the ball after the collision.
