Integrated Concepts A 2.50-kg fireworks shell is fired straight up from a mortar and reaches a height of 110 m. (a) Neglecting air resistance (a poor assumption, but we will make it for this example), calculate the shell's velocity when it leaves the mortar. (b) The mortar itself is a tube 0.450 m long. Calculate the average acceleration of the shell in the tube as it goes from zero to the velocity found in (a). (c) What is the average force on the shell in the mortar? Express your answer in newtons and as a ratio to the weight of the shell.

Can you solve this? With draw an illustration of the given situation below then solve the problem.
6. A rocket is to be fired vertically upward. The initial mass is Mo, the exhaust
velocity
After a total mass AM is exhausted, the rocket engine runs out of fuel. Neglect-
ing air resistance and assuming that the acceleration g of gravity is constant,
set up and solve the equation of motion, and show that if Mo, u, and AM are
fixed, then the larger the rate of exhaust A, that is, the faster it uses up its fuel,
the greater the maximum altitude reached by the rocket.
-u is constant, and the rate of exhaust (dM/dt)
A is constant.
