Four forces act on an object, given by F1= 40 N east, F2= 50 N north, F3=70 N west, and F4= 90 N south. What is the magnitude of the net force on the object? O (a) 50 N O (b) 70 N O (c) 131 N O (d) 170 N (e) 250 N

Two coplanar forces F1 and F2 are acting on an object. F1 has a magnitude of 10N directed at an angle 45 degrees to the positive x axis. F2 has a magnitude of 15 N directed at an angle 120 degrees to the positive x axis. What is the magnitude and direction of the resultant force ?

2 crates are connected to each other by a rope. One crate(m=17kg) is sitting by the ledge of a cliff, and has a coefficient of friction between itself and the ground of 0.21. The second crate(m=11kg) is hanging off the edge of the cliff. Assuming that the hanging crate is heavy enough to pull the crate by the ledge to the right. Find a) and b) and Draw FBD for each crate T-E1. a) The acceleration of the system b) The tension force that connects 2 crates together Paragraph I

A mountain climber, in the process of crossing between two cliffs by a rope, pauses to rest. She weighs 525 N. As the drawing shows, she is closer to the left cliff than to the right cliff, with the result that the tensions in the left and right sides of the rope are not the same. Find the tensions in the rope to the left and to the right of the mountain climber. 80.0⁰ TL = TR= Mi i -65.0⁰ 18 < < |

Two people are pushing a truck across a parking lot. The truck has a mass of about 2 × 103 kg. First, they take turns pushing. When Person A pushes the truck, the truck accelerates at a rate of 1 m/s2. When Person B pushes the truck, it accelerates at a rate of 2 m/s?. (a) Both people stand behind the truck and push in the same direction. What is the net force on the truck? At what rate will the truck accelerate? (b) Person A stands at the back of the truck and Person B stands at the front, and they push in opposite directions. What is the net force on the truck? At what rate will the truck accelerate? In what direction? For both (a) and (b), draw a picture indicating the forces applied by A and B as well as the motion of the truck.

Problem 6: A person is pulled away from a burning building as in the figure to the right. Their mass is 77 kg. There is no net force on them. What are the magnitudes of the tensions T₁ and T₂? 15° T₁ W T₂ 10°

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?

A block with a mass of 5.84 kg is at rest on an inclined surface. The surface makes an angle of  15.3° relative to horizontal. The block remains at rest. What is the magnitude of the normal force that acts on the block?

An electron is a subatomic particle (m accelerates from an initial velocity of +7.54 x 105 m/s to a final velocity of 2.22 x 106 m/s while traveling a distance of 0.0692 m. = 9.11 x 1031 kg) that is subject to electric forces. An electron moving in the +x direction The electron's acceleration is due to two electric forces parallel to the axis: F1 9.04 x 10-17 N, and F2, which points in the -x direction. Find the magnitudes of (a) the net force acting on the electron and (b) the electric force F2 F, F2 F, on with available attempts. (a) Number Units (b) Number Units
