Determine speed when the rocket enters a state of freefall

Reference no: EM13556877

A two-stage rocket accelerates from rest at +3.27 m/s^2 for 6.82seconds. It then accelerates at +2.98 m/s^2 for another 5.90seconds. After the second stage, it enters into a state of freefall.

Determine:
a. the speed when the rocket enters a state of freefall
b. the maximum altitude
c. the height of the rocket after 20.0seconds
d. the maximum speed
e. the total time the rocket is in the air (assumingit is launched from the ground)
