PLEASE HELP ME QUICK A 10.0 kg dog moving at 6.0 m/s to the right collides with a 5.0 kg cat
moving at 3 m/s to the left. If the cat moves to the right at 12.0 m/s after
the collision, what is the speed of the dog?
O 1.5 m/s to the left
O 1.5 m/s to the right
O 3.0 m/s to the left
0 3.0 m/s to the right

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=?
