Avan is traveling on a road at a speed of 55 km/h. a girl
sitting near the driver of the van throws a paper airplane to a
boy at the back of the van with a speed of 2 km/h.
the speed of the paper airplane, to the nearest whole
number relative to a stationary observer on the side of the
road, is
km/h.

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?
