Question 1 12.5 pts Albert tries to move a desk of 27.5 kg of mass that is at rest on a horizontal surface. The desk barely starts sliding as soon as Albert exerts 45.6 N. What is the coefficient of friction between the desk and the surface?Question 2 12.5 pts A toy box of 9.4 kg of mass is being pulled on the floor by Alphonse and Bernard. The coefficients of kinetic and static friction between the box and the horizontal floor are 0.58 and 0.66. If Alphonse exerts 37.2 N and the box acceleration is 1.01 m/s2, what is the force exerted by Bernard?12.5 pts Question 3 What horizontal force F is required to drag a 7 kg block with an acceleration of 4 m/s if a friction force of 29 N opposes the motion? W F12.5 pts Question 4 A horizontal force of 206 N pulls an 18 kg cabinet across a level floor. Find the acceleration of the cabinet if Uk=0.6. FQuestion 5 12.5 pts As shown below, a force of 490 N pushes on a 19 kg box. Starting from rest, the box achieves a velocity of 2.1 m/s in a time of 4.7 s. Find the coefficient of kinetic friction between box and floor
