Question

A 78-kg skydiver has a speed of 62 m/s , what is the kinetic energy?​

Answer 1

it's 149916

Step-by-step explanation:

Formula = 1/2 x m x v^2

so if you put into your calculator 1/2 x 78 x 62^2

you get 149916

Answer 2

149,916J

Step-by-step explanation:

Pneumonic device: Kevin is half-mad and very square

this translates to: KE=(1/2)mv^2 !!

KE=(1/2)(78)(62^2)

KE=(39)(3844)

KE=149,916 Joules
