2 In an experiment to measure the speed of a bee as it flies, a small ball is hung by a thread. When the bee lands on the ball, the ball swings upwards. Scientists record a video of the bee as it lands and analyse the video to determine the height to which the ball swings. mass of bee = 0.25 g; mass of ball = 0.45 g

a The ball with the bee attached to it is found to rise to a vertical height hof 6.0 cm. Calculate its increase in gravitational potential energy.

b Determine the speed of the ball bee when it starts to swing upwards.

c Determine the momentum of the ball+bee.

d Determine the speed with which the bee lands on the ball.

e Suggest the optimum horizontal point of the swing for the bee to take off from the ball. State your criteria for choosing this point and explain your answer.​
