A loaded Costco shopping cart has a weight of 188 pounds(lb). You have to push the cart with a force of 14 pounds(lb) to keep it moving with a constant velocity of 1.1 m/s. What must be the magnitude (absolute value) of the force of friction on the cart?

Frictional force along the direction of motion = 14 pounds

Frictional force is  the resistance force towards relative motion. Frictional Force is a force the equation for which is given by the equation

Weight of the  Castco shopping  cart = 188 Pounds (lb)

Force required to push the cart = 14 Pounds

Uniform velocity of shopping cart = 1.1 m/s

Acceleration in the direction of motion of cart = 0 m/s

So we can say that the forces in direction of motion must be balanced

So the  magnitude (absolute value) of the frictional force along the direction of motion

= 14 pounds

Force of friction = 14 pound

Explanation:

Magnitude = Force / Weight

Magnitude = 14 / 188

Magnitude = 0.074

So,

Force of friction = 14 pound

Force of friction is same as forcee
