A player throws a ball upwards with an initial speed of 29.4 ms-1 (i) What is the direction of acceleration due to gravity during the upward motion of the ball? (ii) What are the velocity and acceleration of the ball at the highest point of its motion? (iii) Choose the x = 0 and t = 0 to be the location and time of the ball at its highest point, vertically downward direction to be the positive direction of x-axis and give the signs of position, velocity and acceleration of the ball during its upward and downward motion.

i) The direction of acceleration due to gravity is downwards. ii) velocity at heighest point is zero. Acceleration due to gravity is equal to 9.8ms-2 iii) during upward motion- Velocity is negative and acceleration is positve. During downward motion- Velocity and acceleration are both positive (Cosidering...
