1. A 9 kg blob of putty moving at 10 m/s collides with an identical blob of putty at rest and they stick together. What speed do they move off together at?
2. A 25 kg boulder moving at 3 m/s collides with an identical boulder at rest and
they stick togethet. What speed do they move off together at?
3. A 40 kg girl and a 60 kg boy are both on ice skates. They push off of each other
and the girl moves at 5 m/s. What is the boy's speed?

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.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
