A crate is dragged across a rough floor by a force of 120n

Problem 1: As a 75 slug car travels along a horizontal, 3200 ft section of road, it changes speed from 5 mph to 60 mph. If the
friction force acting on the car is 25 lbf, what is the total work?

Problem 2: A 180 lbm person climbs a stairway consisting of 150 stairs, each with a vertical rise of 8 inches. How much work does
this person do against gravity?Homework

Problem 3: A crate is dragged across a rough floor by a force of 120N asz` shown below. A friction force of 40N acts to slow the
motion of the crate. If the crate is dragged 25m across the floor

a) what is the work done by the 120 N force?

b) what is the work done by the friction force?

c) what is the net work done?
