A young girl slides down a rope. As she slides faster and faster she tightens her grip increasing the force exerted on her by the rope. what happens when this force is equal in magnitude to her weight?

An experiment was conducted in which many pieces of data were collected. Considering all of the data, the limiting number of significant figures in the experiment was 3 significant figures.

Find the magnitude of the sum of these two vectors

The diagram below shows a horizontal 12. newton force being applied to two blocks, A and B, initially at rest on a horizontal, frictionless surface. Block A has a mass of 1.0 kilogram and block Bhas a mass of 2.0 kilograms. F = 12N A 1.0kg B 2.

A small car meshes with a large truck in a head-on collision. Which of the following statements concerning the magnitude of the momentum change during the collision is correct? (There could be more than one correct choice.

Consider the following distribution of objects: a 3.00-kg object with its center of gravity at (0, 0) m, a 4.20-kg object at (0, 6.00) m, and a 1.40-kg object at (1.00, 0) m. Where should a fourth object of mass 7.

What's the difference between mass & weight & how they are measured

Use the graph of distance versus time to complete the sentences. The cars on the higher track travel the cars on the lower track, in the same time. This means that the cars on the higher track have a average speed than those on the lower track.
