A tortoise and hare start from rest and have a race. As the race begins, both accelerate forward. The hare accelerates uniformly at a rate of 1 m/s for 4.8 seconds. It then continues at a constant speed for 12.4 seconds, before getting tired and slowing down with constant acceleration coming to rest 77 meters from where it started. The tortoise accelerates uniformly for the entire distance, finally catching the hare just as the hare comes to a stop 4)...

A rocket, initially at rest on the ground, accelerates straight upward from rest with constant acceleration 49.0 m/s2 . The acceleration period lasts for time 7.00 s until the fuel is exhausted. After that, the rocket is in free fall. Find the maximum height ymax reached by the rocket. Ignore air resistance and assume a constant acceleration due to gravity equal to 9.80 m/s2 .

A rocket, initially at rest on the ground, accelerates straight upward from rest with constant acceleration 29.4m/s2 . The acceleration period lasts for time 9.00s until the fuel is exhausted. After that, the rocket is in free fall. Find the maximum height ymax reached by the rocket. Ignore air resistance and assume a constant acceleration due to gravity equal to 9.80 m/s2 . Write your answer numerically in units of meters.

A tortoise and hare start from rest and have a race. As the race begins, both accelerate forward. The hare accelerates uniformly at a rate of 1.4 m/s2 for 4 seconds. It then continues at a constant speed for 11.4 seconds, before getting tired and slowing down with constant acceleration coming to rest 84 meters from where it started. The tortoise accelerates uniformly for the entire distance, finally catching the hare just as the hare comes to a stop. 4)...
