At time t = 0, a projectile is launched from ground level. at t = 2.00 s, it is displaced d = 52 m horizontally and h = 55 m vertically above the launch point. what are the (a) horizontal and (b)
vertical components of the initial velocity of the projectile? (c) at the instant it reaches its maximum height above ground level, what is its horizontal displacement d from the launch point?

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?
