Problem

A toy rocket is launched vertically from the ground. The engine provides an upward acceleration of

10\,\text{m/s}^{2}

for

5\,\text{s}

. After

5\,\text{s}

, the engine fails and the rocket continues under gravity alone (

g = 10\,\text{m/s}^{2}

). Draw the velocity-time graph and determine the time at which the rocket reaches its maximum height.
