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?
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 shoe sits on a ramp without moving. As the angle of the ramp is increased, the shoe starts to move. This is because: A) the normal force has increased B) the coefficient of static friction has decreased C) force of gravity on the shoe has increased D) the component of the normal force along the ramp has increased E) the component of gravity acting along the plane of the ramp has increased
