A rescue plane is flying horizontally at a height of 132 m above the ground. The pilot spots a survivor and releases an emergency kit with a parachute. The kit descends at a constant vertical
acceleration of -6.89 m/s and the initial plane horizontal speed is 68.9 m/s. Assuming air
resistance and wind are negligible, how long will the emergency kit be falling through the air?
Answer choices:
• 2.12s
• 7.10s
• 5.33s
• 6.19s

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?
