Question

I don't know how to do the second part.

Answer 1

See below

Step-by-step explanation:

Part B Horizontal velocity = 2.322 m/s ( found in part A)

We need to find when the ball has a VERTICAL velocity that is the same

= 2.322 m/s

vf = a t

2.322 = 9.81 (t) shows t = .237 seconds

NOW:

d = 1/2 at^2

1/2 (9.81) (.237)^2 = .275 meters from the top of the table

1.10 m - .275 m = .825 m from the floor
