KE=.5mv^2
M=mass
v=velocity
.5(4)(100)=200
That should be the answer.
Answer: B. 12.25 W
please give brainliest!
Explanation:
1) Force = Weight = 75 x 9.8 = 735 N
2.)Work = Force x Height = 735 x 5 = 3675 J
3.)Power = Work / Time = 3675 / (5 x 60) = 12.25 W
The group is might be labeled as VIIB or VIIA.
