Which describes an object in projectile motion? o Gravity acts to push the object sideways.
o The object moves in a straight path.
o The forward velocity of the object is 0 m/s.
o The object’s inertia carries it forward.

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?
