Sam, whose mass is 78 kg , takes off across level snow on his jet-powered skis. the skis have a thrust of 180 n and a coefficient of kinetic friction on snow of 0.1. unfortunately, the skis run out of fuel after only 10 s . part a what is sam's top speed?

13.2 m/s

Explanation:

Given

mass of sam

Thrust force=180 N

coefficient of kinetic friction

Force acting on sam is thrust force, friction force

Therefore its top speed is

v=u+at

here u=0 initial velocity

you have to draw the persons position over there

force tends to be low and long diustance masses are high
