A ball is projected horizontally from the edge of a table that is 1.15 m high, and it strikes the floor at a point 1.70 m from the base of the table.
(a) What is the initial speed of the ball?
m/s
(b) How high is the ball above the floor when its velocity vector makes a 45.0° angle with the horizontal?
m

Please show your work.
For part (a), Divide the 1.70 m horizontal displacement by the time required to hit the ground.
For part (b), find out where Vy = Vx = the value in part (a)
