1. a golf ball rolls up a hill toward a miniature-golf hole. assume that the direction toward the
hole is positive.
a. if the golf ball starts with a speed of 2.0 m/s and slows at a constant rate of 0.50 m/s, what is
its velocity after 2.0 s?
b. what is the golf ball's velocity if the constant acceleration continues for 6.0 s?

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?
