A boy wants to use his slingshot to shoot water balloons into the air. His sling slingshot has a spring constant of 40 n/m and he pulls it back 1.5 m before releasing the water balloon and launching it into the air. If air resistance can be ignored and the water balloon has a mass of 1 kg, what is the approximate maximum height that the water balloon can reach? Recall that g= 9.8 m/s

Critical mass is the of material required to produce a chain reaction. a.) minimum amount b.) atomic mass c.) precise amount d.) maximum amount

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
