Answer 2.1 please, using ODE’s
2. A ball is kicked upward with an initial velocity of 20m/s from the roof of a building 30 m high.
Using g = 9.81 m/s² and neglecting air resistance, find:
2.1 The ODE describing this motion
2.2 The maximum height above the ground reached by the ball
2.3 The time that the ball hits the ground, assuming that the ball misses the building on its
way down.
