Two snowmobiles, frosty and snowflake, of equal masses suffer a rear-end collision. just before the collision, frosty's velocity is 25 m/s east and snowflake's velocity is 10 m/s in the same firection. just after the collision, frosty is moving 13m/s towards the east.

a. what is snow flakes velocity immediately after the collision?

b. was this an elastic collision? justify your answer by calculation.

. i am sooo lost..

A. 22

B. NO

Explanation:

A.

During a collision , the net external force on the system is zero .

hence , the total momentum of the system can be CONSERVED .

let the mass of frosty and snowflake be m ;

initial velocity of frosty be = 25 final velocity of frosty be = 13 initial velocity of snowflake be = 10 final velocity of snowflake be = x

therefore from principle of conservation of momentum ,

so ,

answer for A. 22

B.

The collision is NOT ELASTIC.

this is because if it had been elastic , the coefficient of restitution should have been 1 but it isnot i.e

≠ 1

thus it's an inelastic collision.

Iread this book last year so take this with a grain of salt.gene jumps from the tree to compete with finny due to the fact that gene is always trying to do better than finny. he is put under the grasp of peer pressure due to finny almost forcing him to do this. ever since he first jumped finny kept pressuring him to jump since he thought gene enjoyed jumping.rather than uses this answer you should probably just reread chapters 3-4

The answer is b hope this
