Given that an air rocket is fired vertically into the air, lets solve for the following:
(b), At the highest height, the velocity of the rocket will be zero
The rocket's velocity will be zero when it gets to its highest height.
(c) The acceleration of the rocket during its flight will be the negative of the acceleration due to gravity.
This is because, as the rocket goes up, the force of gravity acts on the rocket.
Therefore, the acceleration of the rocket is -9.8 m/s².
ANSWER:
(b) The velocity is zero when it get's to its highest point.
(c) -9.8 m/s²
