A horizontal net force is exerted on a 2.0 kg object at rest. The object starts at x=0 m and travels 8.0 m along a horizontal frictionless surface. What is the velocity of the object
Round answer to 2 significant digits
_ m/s

There's a constant force of 35 N exerted on the object of mass 2.0 kg, so it undergoes an acceleration a of

35 N = (2.0 kg) a   →   a = 17.5 m/s²

The object travels 8.0 m, so that it attains a velocity v of

v ² = 2 (17.5 m/s²) (8.0 m)   →   v ≈ 16.73 m/s ≈ 17 m/s

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
