Which mass has the greatest gravitational potential energy with respect to the floor? (1) a 50.-kg mass resting on the floor
(2) a 2.0-kg mass 10. m above the floor
(3) a 10.-kg mass 2.0 m above the floor
(4) a 6.0-kg mass 5.0 m above the floor​

Suppose that a mass of 2 kg is attached a spring whose spring constant is 50. the system is damped such that b = 12 . the mass is set in motion with an initial velocity of -8 m/s at a position 0 meters from equilibrium. set up and solve a differential equation that models this motion. write your solution in the form a cos ( ω t − α ) where α is a positive number. use your solution to fill in the information below: what is the amplitude of the motion? what is the value of ω ? what is the phase shift?

Which model displays the change in a gas when the temperature of the gaseous system decreases?

Acar jack with a mechanical advantage of 6 needs to produce an output force of 600 n to raise a car. what input force is required? 6 n 100 n 600 n 3,600 n
