Question

What is the minimum work needed to push a 850 -kg car 840 m up along a 9.5 ∘ incline?

science physics

Answer 1

Answer #1

Work needed will be equal to change in potential energy of car.

Work= mgh (where h is vertical height)

= 850*9.8*840*sin(9.5°)

=1154871.108 Joules

A mass m = 17 kg is pulled along a horizontal floor with NO friction for a distance d =6 m. Then the mass is pulled up an incline that makes an angle θ = 37° with the horizontal and has a coefficient of kinetic friction μk = 0.4. The entire time the massless rope used to pull the block is pulled parallel to the incline at an angle of θ = 37° (thus on the incline it is parallel...
