Question

This is the kinetic energy of a 14 kg object travelling at 10 m/s.

Answer 1

700 joules

Explanation:

Basically,

The KE formula is this KE=1/2mv^2

So we substitute the mass for m and the meters per second for v (velocity)

`(1)/(2) (14)(10^2)`

Use PEMDAS, one half times 14 is 7

10 squared is 100,

100*7 = 700

Thanks me later :)
