- A crate remains stationary after it has been placed on a ramp inclined at an angle with the horizontal. Which of the following statements must be true about the magnitude of the frictional force that acts on the crate? (a) It is larger than the weight of the crate. (b) It is at least equal to the weight of the crate. (c) It is equal to sn. (d) It is greater than the component of the gravitational force acting down the ramp. (e) It is equal to the component of the gravitational force acting down the ramp.arrow_forwardA force F applied to an object of mass m1 produces an acceleration of 3.00 m/s2. The same force applied to a second object of mass m2 produces an acceleration of 1.00 m/s2. (a) What is the value of the ratio m1/m2? (b) If m1 and m2 are combined into one object, find its acceleration under the action of the force F.arrow_forwardAn object experiences no acceleration. Which of the following cannot be true for the object? (a) A single force acts on the object. (b) No forces act on the object. (c) Forces act on the object, but the forces cancel.arrow_forward
- An elevator carrying a person of mass m is moving upward and slowing down. How does the magnitude F of the force exerted on the person by the elevator floor compare with the magnitude mg of the gravitational force? a F < mg b F > mg c F = mg d F can be greater than or less than mg, depending on the speed of the elevator.arrow_forwardConsider the Washington Monument in Washington, D.C. in the United States. What forces act between it and the Earth and how do they compare? a) The monument is attracted to the Earth with a force equal to its weight, and the Earth is attracted to the monument with a force equal to the Earth’s weight acting in the same direction. b) The monument is attracted to the Earth with a force equal to its weight, and the Earth is attracted to the monument with a force equal to the Earth’s weight in the opposite direction. c) The monument is attracted to the Earth with a force equal to its weight, and the Earth is attracted to the monument with an equal force in the same direction. d) The monument is attracted to the Earth with a force equal to its weight, and the Earth is attracted to the monument with an equal force in the opposition direction.arrow_forwardGive reasons for the answers to each of the following questions: (a) Can a normal force be horizontal?(b) Can a normal force be directed vertically downward?(c) Consider a tennis ball in contact with a stationary floor and with nothing else.Can the normal force be different in magnitude from the gravitational force exertedon the ball?(d) Can the force exerted by the floor on the ball be different in magnitude fromthe force the ball exerts on the floor?arrow_forward
- How do you find the normal force between a table with a mass of 35 kg and the floor? (Assume that normal force and gravity are the only two vertical forces.) Your answer: The normal force is the same number - 35 kg. Multiply the mass by the coefficient of friction. Multiple the mass by gravitational acceleration (g = 9.8 m/s²) The normal force is zero because the table isn't moving vertically. The normal force is 9.8 N because it is on Earth.

A breeze blowing on the flea parallel to the ground exerts a force of 0.660 x 10-6 N on the flea. Find the direction and magnitude of the acceleration of the flea if its mass is 6.50 x 10-7 kg. Do not neglect the gravitational force.

- According to Newton's second law, when the same force is applied to two objects of different masses, The object with greater mass will experience a greater acceleration and the object with less mass will experience a smaller acceleration. The object with greater mass will experience a great acceleration and the object with less mass will experience an even greater acceleration. The object with greater mass will experience a smaller acceleration and the object with less mass will experience a greater acceleration. The object with greater mass will experience a small acceleration and the object with less mass will experience an even smaller acceleration.arrow_forwardIn the figure here, a box of Cheerios (mass mc = 1.70 kg) and a box of Wheaties (mass mw = 2.60 kg) are accelerated across a horizontal surface by a horizontal force applied to the Cheerios box. The magnitude of the frictional force on the Cheerios box is 2.10 N, and the magnitude of the frictional force on the Wheaties box is 4.60 N. If the magnitude of F is 12.7 N, what is the magnitude of the force on the Wheaties box from the Cheerios box?

True or False (b) The sum of all of the forces acting on a stationary object is the same as an object traveling at a constant velocity. True or False (c) As you increase the angle of a ramp, the coefficient of friction between an object and the ramp also increases. True or Falsearrow_forward
