A puck of mass 0.170 kg slides across ice in the positive x-direction with a kinetic friction coefficient between the ice and puck of 0.152. If the puck is moving at an initial speed of 15.0 m/s, find the following. (a) What is the force of kinetic friction? (Indicate the direction with the sign of your answer.)(b) What is the acceleration of the puck? (Indicate the direction with the sign of your answer.) ((c) How long does it take for the puck to come to rest?(d) What distance does the puck travel during that time?(e) What total work does friction do on the puck? Please outline your steps! I would appreciate it. Explain how you got each answer, please! I would appreciate it!

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.

the answer is 100. i just did this lesson and got a 100% on it. : )
