13.2 min at a constant velocity.

The acceleration of gravity is 9.8 m/s

2

.

What is Shawn’s kinetic energy?

Answer in units of J.​

Answer 1

Speed = distance / time
Speed = 700m / 792s = 0.88383838m/s

0.5 times mass times velocity^2
0.5 times 52.9 times 0.8..^2
= 20.6619541

Not sure if it is actually correct tho
