A 8.0 kg lamp hangs at rest from a single vertical cable. Take g = 9.8 m/s² and upward as positive. What is the cable tension?
A 12 kg crate is lifted straight up by one vertical rope with acceleration 1.5 m/s². Take g = 9.8 m/s² and upward as positive. What is the rope tension?
A 6.0 kg bucket is lowered by one vertical rope with downward acceleration 2.0 m/s². Take g = 9.8 m/s² and downward as positive. What is the rope tension?
A 10.0 kg crate slides at constant speed while one horizontal rope pulls it across a floor. Kinetic friction on the crate is 30 N. What is the rope tension?
A 20 kg cart moves at constant velocity while a rope pulls 30° above the horizontal. Kinetic friction is 52 N. What is the rope tension?
A 4.0 kg block on a frictionless table is joined by a light, inextensible string over a frictionless pulley to a 2.0 kg hanging block. Take g = 9.8 m/s², positive as the hanging block moves down. What is the shared acceleration?
A 5.0 kg mass and a 3.0 kg mass hang on opposite sides of a light, inextensible string over a frictionless pulley. Take g = 9.8 m/s² and positive as the 5.0 kg mass moves down. What is the acceleration magnitude?
A 3.0 kg block on a frictionless table is connected over a frictionless pulley to a 1.5 kg hanging block by a light, inextensible string. Take g = 9.8 m/s². What is the string tension?
A 2.0 kg cart on a frictionless table is tied over a frictionless pulley to a 3.0 kg hanging mass. A 10 N applied force pulls the cart away from the pulley. Take g = 9.8 m/s², positive as the hanging mass moves down. What is the shared acceleration?
A 6.0 kg block on a rough table is connected over a frictionless pulley to a 2.0 kg hanging block. Kinetic friction on the table block is 8.0 N. Take g = 9.8 m/s², positive as the hanging block moves down. What is the tension?
A 7.0 kg mass and a 2.0 kg mass hang from a light, inextensible string over a frictionless pulley. Take g = 9.8 m/s² and positive as the 7.0 kg mass moves down. What is the string tension?
A 200 N sign hangs at rest from two identical cables, each making a 30° angle above the horizontal. What is the tension in each cable?
A 360 N speaker hangs at rest from two identical cables, each making a 60° angle above the horizontal. What is the tension in each cable?
A 500 N banner hangs at rest from two cables. The left cable is 30° above horizontal, and the right cable is 60° above horizontal. What is the tension in the right cable?
A 120 N lantern hangs at rest from two identical cables, each making a 45° angle above the horizontal. What is the tension in each cable?
A 300 N stage light hangs at rest from two cables. The left cable is 60° above horizontal, and the right cable is 30° above horizontal. What is the tension in the left cable?
A light, inextensible string passes over a frictionless pulley connecting two blocks. Which statement matches the ideal-string model?
Two carts are linked by a taut, inextensible rope and start moving along the rope. What prevents one cart from getting ahead of the other?
When drawing separate free-body diagrams for two blocks joined by a taut string, how should tension forces be shown?
A table block is connected to a hanging mass, and the hanging mass accelerates downward. Take g = 9.8 m/s². Why is the string tension less than the hanging mass's weight?
