Students are lifting a 120 N block up using a lever. The distance from the block to the fulcrum is 2 meters and the distance from the fulcrum to the end that needs to be pushed down by the student is 10 meters. What is the mechanical advantage of the lever based on the location of the fulcrum.
A. 5
B. 10
C. 12
D. 60

we need to know the time interval during which the force acts. impulse of force = momentum change

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
