Find the time when the ball hits the ground
WebAt what time will the ball reach the ground? Set h equal to 0 -> 0=-16t^2+64t+30, solve for t, +- means plus or minus -> (-64+-sqrt (64^2-4*-16*30))/2*-16, t=-0.424s and t=4.424s. … WebAug 7, 2024 · 5.2: Bouncing Balls. When a ball is dropped to the ground, one of four things may happen: It may rebound with exactly the same speed as the speed at which it hit the ground. This is an elastic collision. It may come to a complete rest, for example if it were a ball of soft putty. I shall call this a completely inelastic collision.

WebMay 13, 2024 · The height of a ball thrown straight up from a building is given by h ( t) = − 16 t 2 + 32 t + 48, t seconds after it is thrown. 1) Find the maximum height of the ball. 2) Find the time it takes for the ball to reach the ground. algebra-precalculus Share Cite … WebFind the height of the ball after two seconds: Set t = 2, so h = 3 + 75 t − 16 t = 3 + 75 ( 2) − 16 ( 2) 2 = 89 feet. b. Find the time where the ball hits the ground in the field: Solve for t such that h = 0 as the height above the ground will be zero at the point of impact, so ² 0 = 3 + 75 t − 16 t ² t = 4.73 seconds. c.
