A 0.0200-kg rock is shot directly upward with an average force of 98.0 n. The rock accelerates through a distance of 0.150 m.
a.) Determine the acceleration while in the slingshot.
b.) What is the velocity with which it leaves the slingshot?
c.) What force acts on the rock after it leaves the slingshot and what is its value?
d.) What is the value of the acceleration/deceleration after it leaves the slingshot?
e.) How far upward does it travel before it begins to fall?
f.) How long is the rock in the air upon returning to the level of the slingshot?
The Attempt at a Solution
I've tried v= v0+ at for part a; however, my Physics teacher said I was so wrong. Could you help with with this problem? I've tried everything, and I can get the rest of the worksheet. It's just this problem that makes my head spin around like Linda Blair...
Thanks so much and have a great day!!!! :)
