3. An object of mass m is thrown vertically upwards form the Earth's surface with a speed v Assume the object starts at y(0)-0 when t-0s. 3.1 Conceptualise the problem. 3.2 Use Newtons Second law of motion to find the position of the object as a function of time. 3.3 Show the that the maximum height the object reached is given by y(t) - 29 (2) (4)
