Post by: GollumOfOz on Jul 5, 2017 A ball is projected upward at time t = 0.00 s, from a point on a roof 70 m above the ground and experiences negligible air resistance. The ball rises, then falls and strikes the ground. The initial velocity of the ball is 28.5 m/s. Consider all quantities as positive in the upward direction. The velocity of the ball when it is 39 m above the ground is closest to
A) -38 m/s. B) -30 m/s. C) -23 m/s. D) -15 m/s. E) -45 m/s. Title: Re: A ball is projected upward at time t = 0.00 s, from a point on a roof 70 m above the ground and ... Post by: smith239 on Jul 5, 2017 Content hidden
