A 600 kg cannon is used to fire a 15kg cannonball to the right at a velocity of 500 m/s. What is the cannonball’s final momentum in kg*m/s?

How have the competing explanations' experiments on atoms affected the development of the atomic model?

Use the right-hand rule for magnetic force to determine the charge on the moving particle. this is a charge.

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?
