10. Clearly the cat in the above question did not think this attack through to its logical conclusion. Using the concepts find the speed with which the cat will land in the soft earth 10m below the balcony floor. ( note, no cats were hurt in the writing of this problem) 11. A 4.4kg bowling ball and a 347g softball are both fired vertically up into the air at the same speed (3.4m/s). Which object will reach the ground at the greatest speed? Explain your answer. 12. A 245kg satellite is in a circular orbit around the earth (6628 km above the centre of the earth). What is the work done on the satellite by the earth? 13. A 23 456kg truck changes its velocity from 4.6m/s[E] to 5.1m/s[E] over a displacement of 37m[E]. What was the power needed to accomplish this? 14. A driver allows his car to coast up a 3.4m high rise in the road. If the vehicle reaches the crest of the hill at 35.6km/h and the car lost 27% of its energy to various forms of friction, how fast must it have been travelling at the bottom of the hill prior to the ascent?
