Question

Sam, whose mass is 86kg, takes off across level snow onhis jet-powered skis. The skis have a thrust of 300N and a coefficient of kineticfriction on snow of 0.14.Unfortunately, the skis run out of fuel after only 15 s. What is Sam's top speed? How far has Sam traveled when he finally coasts to astop? Sam, whose mass is 86kg, takes off across level snow onhis jet-powered skis.

Explanation / Answer

mass = 86 kg

Ft = 300 N

Coefficient of Kinetic friction = 0.11

Time=13s

Ft = ukmg

86(a)=300-(0.11)(86)(98)=92.7

86(a)=207.3

a=2.41m/s^2
