10) When a car makes a turn at a constant velocity, on a flat level road, does the car experience a net force while making the turn? (Be careful Canvas my not have the same order for the answers) No, because the frictional force is equal to the centripetal force. No, because the speed is constant. Yes, it is the frictional force and is directed towards the center Yes, it is the frictional force and is directed outward away from...

A storeho use worker pushes a box with a refrigerator (mass:96.0-kg) at constant velocity for a distance of 11.0 m. He pushes in the direction parallel to the horizontal floor. A 250.0-N frictional force opposes the motion of the box. Use Newtons second law and definition of work to answer the questions below. (a) (1 point) What is the acceleration of the box? as (b) (2 points) What is the net force, acting on the box? Write down Newtons second...

A man pushes on a 75.0 kg box such that his force of 225 N is exerted at an angle of 27.0o to the horizontal as shown. (a) If the floor exerts a frictional force of 44.0 N on the box, what is the net force acting on the box? (b)If the box is initially at rest, how far will it have been pushed in 5.00 s assuming those forces continued?
Two playful cats are pushing on either sides of a 3.0 kg box that can move...
Two playful cats are pushing on either sides of a 3.0 kg box that can move over a very slippery floor. The black cat pushes with a 9.0 N force, acting due east, while the yellow cat uses a 8.7 N force, pushing 49° north of west. What is the magnitude of the box's acceleration? Assume that the cats are pushing perfectly horizontally to the floor (no vertical forces).

A 110-kg box on the right and a 50-kg box on the left are tied together by a horizontal cable. The 110-kg box is acted upon by an external force of 600 N to the right. The frictional force exerted by the floor on the 110-kg box is 40 N and the frictional force exerted by the floor on the 50-kg box is 10 N. What is the magnitude of the tension in the connecting cable?
