A model of rocket weighing 0.2 lbs is initially at
rest at time t = 0 when launched vertically
upwards using a propulsive force of 2 lbs. This propulsive force is
applied from 0 <t ≤ 1 sec.
When t> 1 sec, the propulsive force stops acting. By neglecting
the resistance of the air and assuming that the
mass of the rocket remains constant, determine
a) The time required for the rocket to reach its
maximum height.
b) The maximum...
