Compute all parts of following question:
Question: 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?
(a) ____kJ;
(b) ____kJ.
I need help to find the work done by the gravity on the shell between it leave the canon to the highest point that it reaches.
