Which of the following has the least amount of kinetic energy?
2 points

a 10 kg elephant moving at 1 m/s

a 0.5 kg rock moving at 5 m/s

a 0.1 kg balloon moving at 7 m/s

a 0.4 kg bunch of feathers moving at 6 m/s

a 10 kg elephant moving at 1 m/s

Explanation:

because kinetic energy depend on how fast an object moves and also depend on the gravitational force which include the weight.

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
