1. What is the Kinetic Energy of a 260 kg object that is moving with a speed of 26 m/s?

Explanation:

so you just have replace the figures were they is mass replace with 260 and were they is velocity replace with 26squared then if you square the 26 you will get 676 then multiply everything you will get the answer

b. lifting dumbbell weight at 20-degree angle from the body after a 45-degree angle

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
