Answer:
Key concepts:
Work = Force * displacement
Frictional force = coefficient of friction * normal force
work = force * displacement
2.95J = f * 1m
f = 2.95 Newtons
Force (friction) = coefficent of friction * normal force (weight)
Normal force = weight = mass * gravity = 1*9.8 = 9.8 newtonss
2.95 newtons = coefficent of friction * 9.8 newtons
