Question
2.3 m n(6 kg) down a hill. When the toboggan reaches the bottom of the slope at B, Hollie gets mad and pushes Rick off the back with a horizontal velo Hollie (48 kg) and Rick (59 kg) ride a toboggan of 1.5 m/'s to the right relative to the toboggan. Use left as the positive direction and neglect friction in all calculations EXAMPLE Answer Chk History art Description What is the velocity of the toboggan A: 6.75 m/s immediately before Rick is pushed C: 6.718 of? m/s Cinclude units with answer) What is the velocity of the toboggan 148 B.after Rick is pushed of Cinclude units with answer) 7, 39 ata, 103% | what is the velocity of Rick after he -25- tnes: 2 C. is pushed offn Cinclude units with answer)Explanation / Answer
A) v = sqrt (2gh) = 6.718 m/sec
B) Momentum conservation
65*6.718 = 6v-59*1.5
v= 87.53 m/sec towards the left
C) Speed of rick = 6.718 + 1.5 = 8.32 m/sec towards the right (ans)
