Where does the pendulum have 100 J of kinetic energy? How many joules of potential energy does the pendulum have at this point?

Simple machines can a. increase force only b. decrease force only c. increase or decrease force

Mutt and jeff are running along a path each pushing a cart loaded with rocks. if mutt's wagon has a mass two times greater than jeff's and they want to stay together, arriving at their destination at the same time, what must happen? a) jeff should slow down so mutt can catch up. b) mutt must use half as much force to push his cart. c) mutt must use twice as much force to push his cart. d) mutt and jeff will use the same force, but mutt will take bigger steps.

Find the mass by adding the numbers from the three sliders
