If it takes a human cannonball 1.5s to exit a 1.6m long cannon, what is the average net force acting on the perfomrer if his mass is 65kg?
The answer for this is 92N. I don't understand why.
A supertanker of mass 1.0 x 10^8 kg travels 3.5km, reaching a speed of 4.1km/h from rest. What was the magnitude of the unbalanced force acting on it?
The answer for this is 1.9N x 10^4
Explain please?!
THANKS!
