Tarzan plans to cross a gorge by swinging in an arc from a hanging vine (Fig. 5-42). If its wings are able to exert a force of 1150 N on the vine, what is the maximum speed it can tolerate at its lowest point of oscillation? Its mass is 78 kg and the vine is 4.7 m tall

The force will determine the acceleration.

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p

Mechanical energy is when the amount of kinetic and potential energies added together remains the same. conserved created lost
