A tow truck is applying a 955 N force at the horizontal to a 415 kg cart as shown. The frictional force between the cart and the road is 407 N..
Calculate the magnitude of the acceleration of the cart. *

Animals respond in various ways to stimuli detected through their senses. some of these responses are stimulated by the presence of danger. which of these animal responses is the best example of a response to an immediate threat? a) a rooster crows every morning at the first sign of light. b) as something approaches an octopus, it shoots a cloud of ink. c) from late fall until spring, bears hibernate to preserve energy. reactivate d) a dog is getting hot in the sunlight, so he moves to a shaded area.

An object moves from position +34m to the position -15m in 15 seconds. what is the total displacement? what is the total velocity?

Polly is pushing a box across the floor with a force of 30 n. the force of gravity is –8 n, and the normal force is 8 n. which value could describe the force of friction if polly could not move the box?
