1-a- A student throws a stone straight upward with an initial speed v, and 1.5 m from the floor. Calculate the initial velocity if the stone reach a maximum height of 5 m. Calculate the total time that the stone will take to hit the floor.
b- A train starts from rest and accelerates uniformly with a = 2 m/s2 until it has traveled 1 km. The train then moves at a constant velocity of 20 m/s for one hour. The train then slows down uniformly at 0.05 m/s2, until it stop. Calculate:
- Maximum speed of the train
- The total distance traveled by the train.
