You (50.0-kg mass) skate on ice at 5.0 m/s to greet your friend (40.0-kg mass), who is standing still, with open arms. as you collide, while holding each other, with what speed do you both move off together? how much kinetic energy is lost in this collision?

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.

A1.5m wire carries a 2 a current when a potential difference of 52 v is applied. what is the resistance of the wire?

If a hiker that weighs 600 newtons climbs a 50 meter hill, how much gravitational potential energy has the hiker gained?
