To see if your results are reasonable, you can compare the final velocity of the stone as it falls down unwinding the wire from the pulley, to the velocity the stone would have if falling the same distance while unconnected to the pulley. What is the velocity of an untethered stone after falling 0.663 m from rest?

3.6 m/s

Explanation:

We are given that

Initial velocity of free falling body,u=0

Distance, h

We have to find the velocity of an untethered  stone after falling 0.663 m

Where

Substitute the values

Hence, the velocity of an untethered  stone after falling 0.663 m=3.6 m/s

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.
