A car with a mass of 1000 kg is traveling at 20 m/s and is brought to a stop over a time period of 25 seconds. How much force is required?
O 800 N
O 1.250 m/s
O 800 sec
O 1.250 N

Is there a point between a 10 nc charge and a 20 nc charge at which the electric field is zero?

As the distance from a magnet increases, what happens to the magnet force?

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.
