There's 2.

1) A 1200-kg airplane starts from rest and, with a constant average forward acceleration of magnitude 5.0m/s^2, reaches its take off speed in 9.00 s. The runway is 300 m long. What is the planes takeoff speed?

2) A boy is attempting to swim directly across a river. He is able to swim at a speed of .500 m/s relative to the water. the river is 25.0m wide and the boy end up at 50.0m downstream from his starting point. How fast is the current of the river?
