A 265-kg load is lifted 18.0 m vertically with an acceleration a = 0.140 g by a single cable. Determine the tension in the cable.

A book is sitting at rest on a horizontal desk. Which statement best describes the normal force acting on the book?

Why is the support force on an object often called the $\mathrm{normal}$ force?

A roller coaster car of mass $m$ passes over a hill at point $d$ with speed $v$. The radius of curvature of the hill at point $d$ is $r$. What is the normal force exerted on the rider when passing point $d$?

Three identical boxes A, B, and C rest on horizontal surfaces. Box A is on a flat table, box B is on the same table with an additional weight placed on top, and box C is on the same table with someone pulling upward on it with a rope (but not lifting it off the table). Rank the boxes in order of the magnitude of the normal force acting on them, from greatest to least.

The Mars Rover Perseverance weighed about 10,000 N while on Earth. After it reached the surface of Mars, it weighed about 3790 N. What is the gravitational acceleration on Mars?

A 3-kg bucket is being pulled upwards by a cord. The tension in the cord is 35 N. What is the acceleration of the bucket? (The mass of the cord is negligible, which means you can assume m_cord = 0.)
