A small car (mass 380 kg) is pushing a large truck ( mass 900 kg) due east on a level road. The car exerts a horizontal force of 1200 N on the truck. What is the magnitude of the force that the truck exerts on the car?

Two people are pulling a heavy 95 kg box across the floor as shown in the figure. Person A is pulling in the x-direction only with a force of 20 N. Person B is pulling at an angle e = 40° above the x-direction, also with a force of 20 N. What is the total pulling force on the box in the x-direction?

A 32.7-kg crate rests on a horizontal floor, and a 62.0-kg person is standing on the crate. Determine the magnitude of the normal force that (a) the floor exerts on the crate and (b) the crate exerts on the person.

In Figure (a), a constant horizontal force F is applied to block A, which pushes against block B with a 21.0 N force directed horizontally to the right. In Figure (b), the same force is applied to block B; now block A pushes on block B with a 13.0 N force directed horizontally to the left. The blocks have a combined mass of 12.0 kg. What are the magnitudes of (a) their acceleration in Figure (a) and (b) force F. ? (a) Number i (b) Number i A B (a) Units Units BA (b)

In 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? Number i Unit

A box has a mass of 2.50 kg is at rest on a horizontal frictionless surface. Four forces act on the box. The four forces are: F₁ = 20.0 N (North), F₂ = 30.0 N (East), F3 = 15.0 N (South), and F4 = 40.0 N (West). What is the resulting acceleration of the box? Select one: a. b. C. d. 4.47 m/² @ 26.6° (North of West) 31.3 m/2 @ 26.6° (West of North) 31.3 m/2 @ 26.6° (North of West) 4.47 m/2 @ 26.6° (West of North)

A 1.0-kg block slides on a rough horizontal surface. A force, P = 9.0 N, is applied to the block at an angle to the horizontal as shown. The magnitude of the block's acceleration along the surface is 3.5 m/s?. What is the magnitude of the force of friction acting on the block? 30° 1.2 N 4.3 N 6.5 N O 15 N 7.2 N 9.0 N

Problem 4: Two teams of seven members engage in a tug of war. Each of the first team's members has an average mass of 67 kg and exerts an average force of 1350 N. Each of the second team's members has an average mass of 72 kg and exerts an average force of 1365 N. a) What is the magnitude of the acceleration of the two teams? b) What is the tension in the section of the rope between the teams?

An SUV containing 5 passengers has a mass of 3500 kg. It has a driving force of 2500 N directed west on a perfectly horizontal road. The surface of the road exerts a resistive force of 500 N due east. At the same time, a strong wind is blowing a force of 500 N due east in the opposite direction of the car's drive force. Does the car have any acceleration? If yes, then what is the magnitude and direction of the car's acceleration?

Two forces are acting on a 0.150 kg hockey puck as it slides along the ice. The first force has a magnitude of 0.320 N and points 35.0° north of east. The second force has a magnitude of 0.520 N and points 65.0° north of east. If these are the only two forces acting on the puck, what will be the magnitude and direction of the puck's acceleration? Enter the direction as an angle measured in degrees counterclockwise from due east.  magnitude of acceleration:               m/s2   direction of acceleration:        °
