Question

if the 50 kg object slows down to a velocity of 1 m/s how much kinetic energy does it have 100j 50j 25j or none

Answer 1

`ek = (1)/(2)m {v}^(2)`

`ek = (1)/(2)(50) {(1)}^(2)`

`ek = (1)/(2)(50)`

`ek = 25j`

//

I'm not really sure but I do know that it's not 0 because the object is still moving, even if it's only moving at 1 m/s.
