Zlatina is using a rope and pulley to suspend a mass of 15 kg. She uses a scale to measure the tension in the rope as she changes the angle at which she pulls, while always keeping the 15 kg mass at exactly the same spot Compare the tension in the rope when it makes an angle of 30° with respect to the vertical with the tension in the rope when it makes an angle of 60° with respect to the vertical. Her friend, Zora, now takes an identical mass and attaches hers directly to the ceiling with just a rope. She attaches a second rope to the mass and pulls it until the first rope makes an angle of = 20° with respect to the vertical, always keeping the second rope horizontal and the mass stationary. Find the tension in each rope.

A boy has filled his toy box with all his favorite toys and it trying to drag it across the floor. The toy box has a mass of 35 kg (including the toys) and the child pulls with a force of 24 N at an angle of 30 degrees above horizontal (he is pulling mostly horizontally, but some of the force is pulling up). How will the normal force between the box and the ground change when the boy starts pulling?
In the figure, two blocks are connected over a pulley. The mass of block Ais 8.50 kg and the coefficient of kinetic friction between A and the incline is 0.370. Angle 6 of the incline is 45.0°. Block A slides down the incline at constant speed. What is the mass of block B? Frictionles, massless pulley Number Units
A child's swing is held up by two massless ropes tied to a tree branch. The distance between the ropes at the top of the swing is less than the distance between the ropes at the bottom, so that the ropes hang 14.01° from the vertical (see the picture). If the tension in each rope is 2.4 N, what is the weight of the swing?

Consider the 63.6-kg mountain climber in the Figure below. Assume the given angle of the rope from the rock wall is 33.5 degrees instead of 31 degrees; likewise assume the angle of the climbers legs from vertical is 11.4 degrees instead of 15 degrees. Find the force that the mountain climber must exert with her feet in pounds on the vertical rock face to remain stationary. Assume that the force is exerted parallel to her legs. Also, assume negligible force exerted by her arms. 31 15 Type your answer...

A boy has filled his toy box with all his favorite toys and it trying to drag it across the floor. The toy box has a mass of 35 kg (including the toys) and the child pulls with a force of 24 N at an angle of 30 degrees above horizontal (he is pulling mostly horizontally, but some of the force is pulling up). How will the normal force between the box and the ground change when the boy starts pulling? Your answer: The normal force will increase when he pulls. The normal force will decrease when he pulls. The normal force will stay the same.
