Acar at 0 m/s accelerates at a rate of 8 m/s2. what is the car's final speech at the end of 4 seconds?

We put a force of 50n on an object and the acceleration is 100 m/s². what is the mass of the object?

Avoltaic cell converts chemical energy to

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?
