A 882 N sign is hung symmetrically by 3 cables that each make an angle of 69° to the horizontal. How much is the vertical component of the tension force in each cable? Answer: 294 N Check Correct Marks for this submission: 1.00/1.00. tension force in each cable? Answer: 91.5N Check x

A person whose mass is m = 104.0 kg steps on a mechanical bathroom scale placed on an inclined plane that makes the angle a = 33.7° with the horizontal. What is the reading on the scale? reading: kg

A woman exerts a horizontal force of 145 N on a box with a mass of 37.2 kg If the box doesn't move, what's the magnitude of the static friction force (in N)?

A man pulls a cement block with a force of 450N using a rope that makes an angle of 35.0 degrees above the horizontal. What is the x-component of his pulling force?

M F a A block is pushed up a frictionless incline by an applied force as shown. If F = 29.3 N, M = 3.1 kg, a = 30.7° and B= 30.0°what is the magnitude of the force the plane exerts on the block? Round your answer to 1 decimal place.

Zoologists have studied the mechanics of locust jumping. When a locust jumps, as depicted in the figure, the resultant force R exerted by the hind legs is the sum of two forces. The first force W acts directly downward to support the locust's weight, which is about 0.02 newton. The second force F is for the takeoff; its magnitude is about 0.29 newton, and the direction makes an angle of 55° with the horizontal. W 55° Find the magnitude of the resultant force R = F + W. (Use decimal notation. Give your answer to three decimal places.) magnitude of resultant force R: newton

A rope exerts a force of 50 N on a box to keep it stationary. If the box is on a plane inclined 25° from the horizontal and the coefficient of static friction is 0.29, calculate the normal force exerted on the box.

Rachel pulls a 30.0 kg box across the floor with a rope that makes an angle of 32o with the floor. She pulls with a force of 250 N. The coefficient of friction between the box and the floor is 0.75. What is the acceleration of the box?
