Question

(14) A worker is pulling a cart. The
frictional force between the cart and
the ground is 350N.What is the
minimum force that must be applied
by the worker to move the cart?​

Answer 1

Answer:

guess a cart is moving in +x direction,but friction force's direction is always opposite of actual force.so the minimum force applied by worker is 350N to move cart.

He will apply the force of >350N for moving cart...

so,minimum force applied by a worker is 350N
