A rocket is launched AGAINST gravity from rest with an acceleration of 4 bj m/s2 m/s2 . The engines
last for 10 seconds before they shut off. The rockets keeps flying upwards but it eventually stops due to
gravity. Answer the questions using gravity -9.8 bj m/s2
• Compute the velocity of the rocket RIGHT BEFORE the engines shut off.
• Compute the height the rockets reaches while the engines are still on.
• Compute the time the rocket takes to reach MAXIMUM HEIGHT.
• What is the maximum height the rocket reaches RESPECT to the ground?
