**1. Helo all,**

A horizontal force of 80N acts on a mass of Kg resting on a horizontal surface. The mass is initially at rest and covers a distance of 5m in 0.92s under the action of the force. Assuming there are no energy losses due to air resistance and therefore that the acceleration is constant

**2. F=ma v=s/t P=Fv**

**3. F=80, m=6, a=13.33,**

v= 5 / 0.92 = 5.4347

P = 80 x 5.4347 =

Does this give me the total energy expended?

Thanks in advance

v= 5 / 0.92 = 5.4347

P = 80 x 5.4347 =

__434.776__Does this give me the total energy expended?

Thanks in advance
