You are standing on a skateboard, initially at rest. a friend throws a very heavy ball towards you. you can either catch the ball or deflect the ball back towards your friend (such that it moves away from you with the same speed as it was originally thrown). what should you do in order to minimize your speed on the skateboard? choose one of the following three answers. a) your final speed on the skateboard will be the same regardless whether you catch the ball or deflect the ball. b) you should catch the hall. c) you should deflect the ballthe answer is you should catch the ball to minimize speed. what i need is a math-based and thorough explanation. any formulas you use to prove, show the orignial equation with steps that you used to get to the final one. will rate right away!

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?
