Here's a step-by-step solution to the problem: Let's define upwards as the positive direction and downwards as the negative direction. The acceleration due to gravity is a = -9.8 m/s^2. --- 3.1 Is the object's acceleration at its maximum height UPWARD, DOWNWARD or ZERO? At its maximum height, the object's vertical velocity is momentarily zero. However, the acceleration due to gravity acts continuously on the object throughout its flight (ignoring air resistance). This acceleration is always directed downwards. Answer for 3.1: DOWNWARD --- 3.2 Calculate the: **3.2.1 Magnitude of the velocity at which the object strikes the
