Oh okay. If a ball starts from rest, the initial velocity is zero.
Knowing this, what is your answer for number one?

LonePieceOfToast · Answer

7?

lowkey · Answer

Um, no, zero. Says the ball starts from rest, which means the initial velocity is zero, which means the first one is zero

LonePieceOfToast · Answer

oh I thought you meant
 the second one

lowkey · Answer

Lol the second one 
So to find out acceleration, you use the formula v=at
7=a(4)

lowkey · Answer

a=1.75
