A cannon fires a cannonball at an angle 30 degrees above the horizontal, which flies through the air. It is fired with a net force of 3000 N, and the cannonball is 10 kg. The initial height of the cannonball after firing is 0 m. The cannonball experiences 3000 N of force across the 1 m length of the barrel. What is its velocity after exiting the cannon?

A1000-kg weather rocket is launched straight up. the rocket motor provides a constant acceleration for 16-s, then the motor stops. the rocket altitude 20-s after launch is 510-m. you can ignore any effects of air resistance. a. what was the rocket’s acceleration during the first 16-s? b. what is the rocket’s speed as it passes through a cloud 5100-m above the ground?
