- A factory needs to move packages from one level to another using a ramp. They want to choose a material that has a specific coefficient of friction with the packages that will be sliding down the ramp. What problem could occur if the coefficient of friction were too high? A.Packages would go too fast and could break at the end of the ramp. B.Packages could slow down too quickly and stop before the end of the ramp. C.Packages could break the ramp because gravity would increase. D.Packages could bounce off the ramp because normal force would increase.arrow_forwardV1 Refer to Figure the brakes are released. The coefficient of kinetic friction between the tires and the road is 0.7. A truck is traveling at 31 m/s when the brakes are fully applied causing the wheels to skid for 3 seconds and then What is the final speed of the truck in units of m/s ? O 10.40 O 7.40 O 13.40 O 4.40arrow_forwardA block with mass m sits on a frictionless plane inclined at angle θ, as shown in the figure. If the plane is accelerated to the right with the proper acceleration that causes the blockto remain at the same position with respect to the plane, what is the normal force between the block and the plane? a. mg b. mg sin θ c. mg cos θ d. mg/cos θarrow_forward
- A woman is standing on a steep hillside in the rain and is not moving. A sudden gust of wind blows down the hillside, which makes her worry that she might start sliding down the hill. However, the woman still does not slide. Which of the following statements explains why she does not slide down the hillside? A. The wind does not supply enough force to overcome the kinetic friction between the woman and the ground. B. The static friction between the woman and the ground increases as a result of the wind gust. C. The wind does not supply enough force to overcome the static friction between the woman and the ground. D. The kinetic friction between the woman and the ground increases as a result of the wind gust.arrow_forward21. A child pushes a 315 g toy truck across a horizontal rough surface. (coefficient of kinetic friction, ux = 0.73). a. Draw a formal free-body diagram of the toy truck if it is being pushed horizontally to the right. b.

- Which statement describes the effect of an inclined plane on the amount of force required to push an object? A. Objects require more force to push them up an inclined plane compared to a flat surfaceB. There is no way to predict the effect of an inclinded plane on the amount of force required to push an objectC. Objects require less force to push them up an inclined plane compared to a horizontal surface.D. Objects require the same amount of force to push them up an inclined plane as on a flat surfacearrow_forwardA hockey puck slides with constant velocity, from point “a” to point “b” along a frictionless horizontal surface. When the puck reaches point “b”, it receives a instantaneous horizontal “kick “ in the direction as depicted by the heavy arrow. a) Along the frictionless path you have chosen, how does the speed of the puck vary after receiving the “kick”? *a. No change. b. Continuously increasing. c. Increasing for a while, and decreasing thereafter. d.
