A moving object is in equilibrium. Which best describes the motion of the object if no forces change? It will change directions.
It will slow down and stop.
It will maintain its state of motion.
It will speed up and then slow down.

Awater balloon launcher uses an elastic band with a spring constant of 115 n/m to use thee launcher you stretch thee band back with a balloon n it the water balloons have a mass of 1.3 kg a) if you stretch the band by 0.8 m, what elastic force will the band exert? b) with the band stretched 0.8 m, how much elastic potential energy is stored in the spring? c) if you release the band, it pushes forward. what is the kinetic energy of the balloon when it reaches the natural length of the band? d) what is the speed of the balloon when it reaches the natural length of the band?

This is the number of complete movements of a wave per second.

The force needed to overcome static friction is usually less than that needed to overcome kinetic friction.true or false?
