How much work is done on the ball during the acceleration?

[kelly242]

Homework Statement

A 0.50 kg ball accelerated from rest by a 8.0 N force for 3.0 m

Homework Equations

W=E
Ek= 1/2mv2
Ep=mgh

The Attempt at a Solution

Given: mass= 0.50 Kg, V=0m/s, F=8.0 N, d=3.0 m

Ek=1/2mv²
=1/2(0.50 kg)(0 m/s)²
=o J
That's wrong

How can v be 0 if the ball is being accelerated for a finite period of time? Use the work-energy theorem to calculate the amount of work done on the ball. Since nothing else contributes to the ball's energy, this work must be its kinetic energy.
