Abody is moving with simple harmonic motion. state two conditions that must be satisfied concerning the acceleration of the body. condition 1 condition 2 a mass is suspended from a vertical spring and the system is allowed to come to rest. (b) when the mass is now pulled down a distance of 76 mm and released, the time taken for 25 oscillations is 23 s

You are driving to the grocery store at 20 m/s. you are 110m from an intersection when the traffic light turns red. assume that your reaction time is 0.50s and that your car brakes with constant acceleration. how far are you from the intersection when you begin to apply the brakes? what acceleration will bring you to rest right at the intersection? how long does it take you to stop after the light changes? the known values: vi=20m/s xi=110m t=.50s vf=0m/s xf=0m a=?
