Carla ejerce una fuerza de módulo igual a 250 N sobre un refrigerador, logrando desplazarlo 12 m en una superficie horizontal. Si se desprecia el roce, ¿cuál es el trabajo
realizado por la fuerza, si esta fue ejercida en la misma dirección y sentido que el
movimiento del refrigerador?

Abox is pushed down at an angle of 32 degrees on a rough surface. the box moves to the right.what equation should be used to find the net force in the y-direction? answers: a. fnet,y = fn - fgb. fnet,y= fp - ffc. fnet,y = fn-fg- fpcos(32)d. fnet,y = fn-fg-fpsin(32)

Two cannon balls weighing 18 kg and 24 kg are chained together and fired horizontally with a velocity of 165 m/s from the top of a 21-m wall. the chain breaks during the flight of the cannonballs and the 18-kg cannonball strikes the ground at t = 1.5 s, at a distance of 240 m from the foot of the wall, and 7 m to the right of the line of fire. determine the position of the other cannonball at that instant. neglect the resistance of the air.
