Question: two snowmobiles frosty and snowflake of equal masses suffer a...

Question details

Two snowmobiles, Frosty and Snowflake, of equal masses suffer a rear-end collision. Just before the collision, Frosty’s velocity is 25 m s–1 east and Snowflake’s velocity is 10 m s–1 in the same direction. Just after the collision, Frosty is moving 13 ms–1 towards the east.

a) What is Snowflake’s velocity immediately after the collision? 3 marks

b) Was this an elastic collision? Justify your answer by calculation. 4 marks
