A5.44 kg block initially at rest is pulled to the right along a horizontal, frictionless surface by a constant horizontal force of 7.4 n. find the block's speed after it has moved 4.9 m.

v = 3.65 m/s

Explanation:

It is given that,

Mass of the block, m = 5.44 kg

Horizontal force acting on the block, F = 7.4 N

We need to find the speed of the block after it has moved 4.9 meters. It can be calculated using the work energy theorem as:

v = 3.65 m/s

So, the speed of the block is 3.65 m/s. Hence, this is the required solution.

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
