Thank you! Should I add a normal force exerted upward on the file cabinet if the cabinet is sitting on a flat, wooden floor? How will that change the free body diagram?
by Bartleby Expert- b. A block of mass m is placed at rest on an inclined plane as shown below. The plane is frictionless and makes the angle with the horizontal as shown. If another force of magnitude P is applied to the block at the known angle as shown, draw the free body diagram for the block and determine what the value of P must be if the block is to remain at rest. PThree blocks (as shown in the figure) are released from rest and they start to accelerate with a constant magnitude of 0.44 m/s². Block A has mass M, block B has mass 1.8 M and block C has mass 2.0M. The value of M is not given. What is the coefficient of kinetic friction between the table and block B? The mass and friction in the pulleys can be ignored. A Question Help: Read Submit Question B CTommy is working on a physics problem and asks his friend Sarah to check his work. He is to draw a free body diagram for a man walking to the left and comes up with the following: He reasons, “The man is walking to the left, so the force of friction is acting in the opposite direction. The normal force should be opposite and equal to that of the gravitational force.” Is Tommy correct with his diagram and reasoning? If so, explain. If not, what mistake did he make? Communication throughout the test will also be evaluated on 1) rounding using significant digits, 2) proper use of units, 3) organization and neatness, and 4) showing all work
- question 4A cart of mass 0.85 kg is on a track, connected by a string over a pulley to a hanging mass of 0.1 kg. A friction pad is attached to the bottom of the cart, and you push the cart so that it first moves toward the sensor, then away from the motion sensor. Assuming the magnitude of the force of friction remains constant throughout the entire motion of the cart, the magnitude of the net acceleration of the cart is which of the following? a. larger when the cart is moving towards the motion sensor b. larger when the cart is moving away from the motion sensor c. the magnitude of the acceleration cannot be predictedA meter stick has a mass of 0.30 kg and balances at its center. When a small chain is suspended from one end, the balance point moves 12.0 cm toward the end with the chain. Determine the mass of the chain. 0 x Determine a convenient place for the origin of the coordinate system. See if you can write an expression for the center of mass of the two objects in terms of known quantities and the mass of the chain and then solve for the mass of the chain. g Submit Answer

For each one, find the magnitude (with correct units) and direction of both the net force and acceleration.The center of mass of the arm shown in the figure is at point A. Find the magnitudes (in N) of the tension force F and the force F which hold the arm in equilibrium. (Let 8 = 24.0°.) Assume the weight of the arm is 48.3 N. ↑4 8.00 cm N N - 29.0 cmThree blocks with masses m1 = 2.3 kg, m2 = 6.2 kg and m3 = 1.0kg are connected by a light string that passes over a light pulley as shown in the figure below.

Which choice describes the forces? Assume that the truck is much heavier than the car. A. The truck exerts a greater amount of force on the car than the car exerts on the truck. B. The car exerts a greater amount of force on the truck than the truck exerts on the car. C. Neither exerts a force on the other; the car gets smashed simply because it is in the way of the truck D. The truck exerts a force on the car but the car doesn't exert a force on the truck. E. The truck exerts the same amount of force on the car as the car exerts on the truck. F. Not enough information is given to pick one of the answers above. G. None of the answers above describes the situation correctly.

Beating requires the sailboat to travel in a zigzag pattern at an angle to the wind that is greater than the no-go zone, which is shaded red in (Figure 1). When a sailboat is just outside the no-go zone (boats B in the figure) the wind Part A exerts a force F on the sail that has a component in the direction of motion v. Similar comments apply to boats C. The work done by the wind on the sail is W = Fdcose, and because v = d/t, the propulsion power P = W/t delivered to the sailboat is Fvcose, where 0 is the angle between the sail force and the Assuming that F and v have the same magnitudes for each sailboat, will the propulsion power delivered to sailboats B be greater than, less than, or the same as the propulsion power delivered to sailboats C? direction of motion.

They start by hammering a spike into the stump to give them something to tie on ropes. Assume that both students pull with the same force and rank the following strategies from most to least effective (most effective in the #1 spot). Question 1 options: Tie on one rope and have both students pull on it. Tie on two ropes and have each student pull with a 15 degree angle between the ropes. Tie on two ropes and have each student pull with a 45 degree angle between the ropes. Tie on two ropes and have each student pull with a 60 degree angle between the ropes.
