a) 1. Mr. Balgoo is pushing his Walmart shopping cart full of groceries (m=58 kg) at constant speed with a force of 300N directed along the handle, which is at an angle of 32.5 to the horizontal on a rough surface. A: 10 Schematic diagram here: b) Draw FBDs for the shopping cart. c) The normal force exerted vertically upward on the shopping cart by the ground. d) The horizontal friction force on shopping cart and coefficient of friction between chart & ground? What force must he have to exert on the shopping cart to accelerate it from rest to 4m/s in 5sec, assuming the same friction force? BONUS: In the figure given below a Force of magnitude 12N is applied to a FedEx box of mass m2= 1kg. The force is directed up a plane tilted by = 37. The box is connected by a cord to a UPS box of mass m =3 kg on the floor. Floor and the plane has a coefficient of friction 0.09 but pulley is frictionless, and the masses of pulley and the cord is negligible. Find Fnet, a system and Tension of cord? 11 12.
