An overhead view of the path taken by a ball of mass m as it bounces from the rail of a pool table. The ball's initial speed is v and the angle is a. The bounce reverses the y component of the ball's velocity but does not alter the x component. ... (b) What is the change...
Thank you. When I solved for t, i got .000000004 and I thought it would be like totally okay to just use 4e-9. When I tried it again I got a more specific number by using SN button on my calculator. Using 4.6189e-9 for t, I got the right answer. 8.37855e14
I am working on this problem but I got it wrong. I'm not sure what happened.
