3. What is the total mechanical energy of the sand bag?​

EHTO EXAMPLE NG PROB.

1. A 15.0 g bullet is fired at 840 m/s into a ballistic pendulum consisting of a 24.0 kg bag of sand. If the bag rises to a height of 80.0 cm, how much energy is converted into thermal energy in the bag?

Homework Equations

The Attempt at a Solution

1. Given:m = 24.0 kg h= 80 cm or 0.08 m v= 840 m/s

Required: Thermal energy

Analysis: Determine total mechanical energy as the bag of sand rises and falls.

Bag of sand at the top mgh (24.0 kg)(9.8 m/s^2)(0.08 m ) =18.81 J

At the bottom Ek + Eg 1/2(24.0 kg ) (0.08m) =0.96 Total mechanical energy = 18.81 J - 0.96 = 17.85 J

I am kind of lost with this question and not sure of the right procedure to follow. Thanks for the assistance.
