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?

(2) (a) you have a simple circuit that consists of only a battery (δvbat=1.5v) and two resistors with resistance r1=10ω and r2=5ω, connected in series with each other. what is the current running through the battery? (b) you re-arrange your circuit so now r2 is attached in parallel to r1 rather than in series. what is the current running through the battery? (c) you add an additional resistor r3=7ω on the same branch as r2. what is the current running through the battery? (d) what is the power dissipated in r3?
