Solve the all parts of given problem:
Problem: A canon sends a shell of mass 35.0 kg into air with an initial speed of 135 m/s, in the direction of 55° above the horizontal. If we ignore the effect of air resistance,
Part A: What is the work done by the gravity on the shell between it leave the canon to the highest point that it reaches?
Part B: What is the work delivered by the canon on the shell?
I need help to find the work delivered by the canon on the shell.
