How much force is needed to accelerate a 34 kg skier at 4 m/s2?

Net force needed to accelerate the skier is 136 N

Explanation:

As per Newton's 2nd law we know that net force on the system is product of mass and its acceleration

here we know that

m = 34 kg

so we have

F = ma

since you're a real machine, your ama is always less than your ima, because you can never totally eliminate friction.

the journeys of marquette, joliet and la salle a) new france expand.

all three of these explorers explored the midwest and the area around the great lakes, which they subsequently claimed for france.

this was a big portion of territory and expanded new france which before then only consisted of quebec province in northeastern canada
