#21 please U/5-A designer is trying to determine the type of wire to use for a pendantlight that will hang from the ceiling of an elevator. The wire can withstanda force of 82 N before breaking. Therefore, the upward directed force onthe lamp, called tension, cannot exceed 82 N. The lamp also experiencesa 45-N gravitational force, called weight, in the downward direction. Whatis the maximum upward acceleration the elevator can have before the wirebreaks? The lamp has a mass of 4.6 kg.22 A designer is trying to determine the type of wire to use for a pendant lightthat will hang from the ceiling of an elevator. The wire can withstand a forceof 70.0 N before breaking. Therefore, the upward directed force on the lamp,called tension, cannot exceed 70.0 N. The lamp also experiences a 60.0-Ngravitational force, called weight, in the downward direction. What is themaximum upward acceleration the elevator can have before the wire breaks?The lamp has a mass of 6.1 kg.(23) Two friends are pushing an 18-kg crate across the floor. One of them appliesa force of 75.0 N to the left, and the crate moves at a constant speed. Whatforce must the other person be applying, and in what direction does theforce act?A trapeze is a short, horizontal bar held up by two vertical ropes on eitherside. An acrobat with a mass of 60.0 kg provides a 588-N downward force onthe bar. Each of the two trapeze ropes provides an upward force of 349 N.What is the upward acceleration of the acrobat?25 A horse is dragging a crate behind it. The horse applies a force of 60.0 N toaccelerate the crate to the right, and the crate experiences a 10.0-N forcein the opposite direction due to a force called friction from the ground. Thecrate's acceleration is 0.67 m/s². Determine the crate's mass.24 Marco and his sister are rummaging through a large box of books. Theiryounger brother also wants to see what's inside the box. Marco pulls the boxaway from his brother, applying a force of 38 N to the left. His sister helpshim by applying an additional force of 36 N to the left. Their brother applies aforce of 35 N to pull the box in the opposite direction. The box weighs 22 kg.Determine the acceleration of the box.21 Two dogs are pulling on either end of a toy rope. One dog has a mass of12 kg and pulls to the left with a force of 12 N. The other dog has a mass of18 kg and pulls to the right with a force of 12 N. Determine the accelerationof the rope.O
