Question

Using energy considerations and neglecting air resistance, calculate how far a rock will rise above its point of release if it is tossed straight up with an initial speed of 10m/sec. Using energy considerations and neglecting air resistance, calculate how far a rock will rise above its point of release if it is tossed straight up with an initial speed of 10m/sec. Solved using energy considerations alone.

Answer 1

The initial KE it has is converted to GPE. So at the max height, the GPE=initialKE

mgh=1/2 mv^2

calculate h.

Answer 2

Thank you! I have the answer now! Was working on this problem for 30 mins! Was close but looking for wrong variable! You are awesome Bob!
