3. A cannon with a 200 cm long barrel applies a constant force of 120 N

over the length of the barrel. If a monkey shoots the 2.7 kg cannonball
straight up, what is the maximum height it reaches?

Answer:

the answer is 9.07m.

Step-by-step explanation:

First you need to find the velocity of the ball leaving the cannon.

F=MA

F due to gravity = -2.7*9.8 if the cannon is pointed straight up

120-2.7*9.8=2.7*A
