Sphere is fired downwards into a medium with an initial speed of 27 m/s. If it experiences a deceleration of a
(-6t) m/s2, where t is in seconds, determine the distance traveled before it
stops.​

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?

The strong nuclear force acts over a small distance than the electrostatic force. true or false

If you let go of the notebook after lifting it, will it move? how?
