At the scene of an accident, a police officer notices that the skid marks of a car re 10 m long. The officer knows that the typical deceleration of this car when skidding is -45 m/s^2. What can the officer estimate for the original speed of the car?

A200-n force is applied to the foot-operated air pump. the return spring s exerts a 2.6-n·m moment on member oba for this position. determine the corresponding compression force c in the cylinder bd. if the diameter of the piston in the cylinder is 40 mm, estimate the air pressure generated for these conditions. state any assumptions. enter a positive number for the compression force c.
