Time allowed for this question: ten minutes. Calculators are allowed. Show all working.
1. A pianist (mass 109 kg) was sitting on his stool (height 55 cm) when it inexplicably gave way. How fast was he travelling when he hit the ground?
2. He had drunk 3.5 pints of Ringwoods Old Gut-throbbers ale (SG 1.05). By how much is the answer to question 1 changed?
3. The pianist was leaning back against one of shed 3b's tasteful curtains at the time. The contact area of 0.33 sq.m., the horizontal force exerted by the huge pianist was 18N and the coefficient of friction between expensive Barbour shirt and aforementioned curtain was 0.12. (Assume horizontal force remains constant, and use Coulomb's Law)
a. How fast was the pianist travelling this time when he hit the ground?
b. How long did he take to hit the ground?
4. What percentage of the rest of the Thomas Lord Old Gits stopped at once and offered their sincere sympathy to the pianist, who was by now doing beached whale impression on the floor of Shed 3b?
5. What percentage of the rest of the Thomas Lord Old Gits had to go and change their underwear, having wet themselves laughing?
