A hockey puck with a mass of 0.18 kg is at rest on the horizontal frictionless surface of the rink. A player applies a horizontal force to the puck which causes it to travel 1.25 meters in 5 seconds. What net force is exerted on the puck?

Hello!

Begin by finding the acceleration of the puck. Use the kinematic equation:

The initial velocity is 0 m/s since the object was at rest, so we can rewrite the equation as:

Plug in the given distance and time:

Find the net force using the formula F = m · a (Newton's Second Law)

F = 0.18 · 0.1

F = 0.018 N

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
