a ball is launched upward at an angle from the ground. which way does its acceleration point at the top?

Often called simply "velocity," this is the velocity of an object at a particular moment in time.

Give an example in which the electrical energy changes to light energy

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.
