TIMED - A hydraulic lift is being designed to lift cars. The input piston has an area of 10 cm2 and can handle a force up to 400 N. If the lift must be able to move cars with a mass as large as 1800 kg, what is the smallest size the output piston could be?
0.23 cm2

40 cm2

45 cm2

441 cm2

882 cm2

A100 kg running back runs at 5m/s into a stationary linebacker. it takes 0.5 for the running back to be completely stopped

Dao makes a table to identify the variables used in the equations for centripetal acceleration. what quantities belong in cells x and y?

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=?
