Question 13 A basketball player throws a basketball at a velocity of 10.6 ms and at an angle of 16° above the horizontal The ball be 1.85 m above the ground when the ball is thrown. The basketball hoop is 8.36 m horizontally from the player. 10 1.55 (a) How long does it take for the ball to travel to the hoop? (b) What is the height of the hoop above the ground? (c) The basketball has mass 600 g. Determine the total potential and kinetic energy of the ball at the moment it is thrown Part 2 0.25 kg of ice and 200 litres of water are in thermal equilibrium. (a) How much energy is required to rise the temperature of the mixture to 20°C (b) A 2kW heater is then used to increase the temperature of the mixture from 20°C to 100°C, how long would it take in hours. (c) If the heater was used for 20 hours how much water will be converted to water vapour. (D) How much energy would be required to convert all the mixture to water vapour.
