At t = 0, it is released from rest and has its engines ignited. Its engines generate an acceleration in the positive y-direction which changes with time of magnitude ßt, where = 18.00 m/s³. This acceleration doesn't include the effects of gravity. After 5.00 seconds have passed, the rocket's fuel will run out, and will no longer provide an upward thrust.

- A hot air balloon ascends straight up from the ground with a constant speed of 8.0 m/s. Three seconds later, a stone is shot straight up with an initial speed of 25 m/s. Determine, (a) the times when the balloon and the stone are at the same height.

She then gives it a powerful upward hit from an initial height of 0.80 m and sends it traveling perfectly vertically. After rising to its maximum height, the ball falls back down to the court. Given that the ball was in the air for a total of 1.91 s, determine its velocity upon hitting the court.arrow_forwardCANNOT BE HAND-DRAWN, THE EXPLANATION MUST BE TYPED OUTarrow_forward
