A model rocket, weight 0.50Ibf is launched vertically from level ground. The thrust of its motor is T=3.0Ibf and lasts for 2.4secs. After the motor shuts down, the rocket behaves as a ballistic projectile, reaching maximum height and then crashing to the ground . a & b) Calculate the height and the velocity of the rocket when the motor stops.c) Calculate the maximum height reached by the rocket.d) Calculate the impact velocity of the rocket.
