Finding power when a student lifts 60kg 2.5m in 4 seconds

[dois]

Homework Statement

How powerful is a student who can lift 60kg from the floor to above their head (2.5 meters from the ground) in 4 seconds?

Homework Equations

To find power we would use the equation
P= W/T

The Attempt at a Solution

I'm not sure if we would use the P=w/t equation, and work is an unknown variable, and when I try to find W, W=FxD, Force is also an unknown variable

What is the force on the object due to gravity (this would also be the force required to lift it)?

 

[dois]

Would the force on the object due to gravity be 9.8N
so the Force required to lift it is 9.8 N

 

[downwithsocks]

Force due to gravity is mg. Then use that and the distance to find the work, and the work and the time to find the power.

Keep in mind that the force by gravity is not 9.8 N but rather m(9.8 m/s^2) where 9.8 = g. This would be different if we were on a planet other than our homely earth.
