CLICK HERE TO SEE QUESTION 2 QUESTION 2 A hоt аir bаllооn is аscending at 5 m.s-1. A ball of mass 50 g is dropped over the edge. The ball takes 2,5 s to reach the ground after being dropped. The diagram below illustrates the scenario. Ignore the effect of air friction. The diagram is not to scale. 2.1 What is the acceleration of the ball after it is dropped? (1) 2.2 Calculate the height of the balloon the moment the ball is dropped. (3) 2.3 Calculate the maximum height the toy ball reaches above the ground. (4) 2.4 Show that the velocity of the toy ball as it hits the ground is 19,50 m.s-1 downwards. (4) 2.5 The ball bounces with a velocity of 15 m.s-1 after hitting the ground. 2.5.1 State the work energy theorem. (2) 2.5.2 The bounce is not considered elastic. Explain this answer (2) 2.5.3 Calculate the loss of kinetic energy of the ball during the bounce. (3) 2.5.4 Calculate the height the ball reaches after bouncing. (4) 2.5.5 Draw a position vs. time graph of the motion of the ball from the time of release till its second bounce. Label the graph accurately including all relevant heights and times on the graph. Take the ground as zero and above the ground as positive. (5) 2.5.6 Draw a sketch graph of the acceleration of the ball from the time it is dropped. (4) 2.6 While the balloon was rising someone was recording its vertical ascent velocity with a speed gun. They see the ball being dropped and quickly measures the balls velocity just as it strikes the ground. They record a velocity of 18 m.s-1. 2.6.1 Giving suitable reasons, why do you think the velocity of the ball striking the ground is not the same as the velocity from Q 2.4 (3) [35]
