Kinetic Energy/work finding the distance
A 12 kg block is sliding to the left across the floor at a speed of 18 m/s. Opposing the
motion is a 50 N force. How far (in m) will the object travel before its speed is reduced
to 8 m/s?
(e) none of these
2. Relevant equations[/b]
lost on how to find distance tho..
K.E. = 1/2mv^2
3. The attempt at a solution
I got d but not sure...i thouhght it was d 7.68 round up
