M Alt Alt LATITUDE E6430 Name: Directions: All problems must be solved using the problem-solving method, givens, unknowns, equation, cubstitution, and solve with correct unit to receive full credit. Also, all force problems require an FBD. P.4D-Practice-Force of Friction 1. A 38 kg crate rests on a floor. A horizontal pulling force of just more than 170 N is needed to start thecrate moving. What is the coefficient of static friction between the crate and the floor?

a boy at the school is pulling his 20kg stroller bag at a constant speed by holding the strap at an angle above the horizontal. he is pulling the handle with a 35 N force and the friction force on the stroller bag is 20 N. 1. draw a FBD 2. identify the angle that is made with the horizontal 3. wat is the magnitude of the normal force the ground produces on the stroller bag?

How would I drawl a diagram for this question?

A supermarket pushcart is being pushed at 45 degrees with respect to the horizontal from the starting point to the cashier, which is 25 feet away. The cart is 5kg, it contains 2 boxes of 10-1b flour and seven packs of half-kilogram sugar. The coefficient of friction between the wheels and the floor is 0.03. a. What force is required? b. How much force is required?
