An 85 kg cheerleader stands on a scale that reads in kg.

b. What does the scale read if the 85 kg cheerleader lifts the 50 kg cheerleader upward with an acceleration of 2.0 m/s²?

Taylor exerts a greater amount of force on Josh than Josh exerts on Taylor.

Josh exerts a greater amount of force on Taylor than the Taylor exerts on Josh.

It depends upon exactly how Taylor pushes.

Taylor exerts the same amount of force on Josh as Josh exerts on Taylor.

Taylor (150 lbs.) and Josh (200 lbs.) are standing on frictionless ice. Taylor pushes on Josh. During the push which person exerts the greater force on the other?

Newton's Three Laws of Motion (Clear and Easy to Follow)

A 1000 kg car is pushing an out-of-gear 2000 kg truck that has a dead battery. When the driver steps on the accelerator, the drive wheels of the car push horizontally against the ground with a force of 4500 N. Rolling friction can be neglected. (a) What is the magnitude of the force of the car on the truck?

A 75 kg archer on ice skates is standing at rest on very smooth ice. He shoots a 450 g arrow horizontally. When released, the arrow reaches a speed of 110 m/s in 0.25 s. Assume that the force of the bow string on the arrow is constant.

b. What is the archer's recoil speed?

Josh experiences a greater acceleration than Taylor.

Taylor and Josh have the same acceleration.

It depends upon exactly how Taylor pushes on Josh.

Taylor experiences a greater acceleration than Josh.

Taylor (150 lbs.) and Josh (200 lbs.) are standing on frictionless ice. Taylor pushes on Josh. During the push who experiences the greater magnitude of acceleration?

(b) How much force does the astronaut exert on his chair while accelerating straight up at 10 m/s^2?

The foot of a 55 kg sprinter is on the ground for 0.25 s while her body accelerates from rest to 2.0 m/s. (b) What is the magnitude of the friction force?

A small car of mass 380 kg is pushing a large truck of mass 900 kg due east on a level road. The car exerts a horizontal force of 1600 N on the truck. What is the magnitude of the force that the truck exerts on the car?

Newton's Third Law & Action-Reaction Pairs

Blocks with masses of 1 kg, 2 kg, and 3 kg are lined up in a row on a frictionless table. All three are pushed forward by a 12 N force applied to the 1 kg block. (b) How much force does the 2 kg block exert on the 1 kg block?

A house painter uses the chair-and-pulley arrangement of FIGURE P7.45 to lift himself up the side of a house. The painter's mass is 70 kg and the chair's mass is 10 kg. With what force must he pull down on the rope in order to accelerate upward at 0.20 m/s².

The force of the ground on the ball is greater than the force of the ball on the ground.

The force of the ball on the ground is greater than the force of the ground on the ball.

There is not enough information to answer this question because we don't know the mass of the ball.

The force of the ball on the ground is exactly the same as the force of the ground on the ball.

Ryan bounces a small rubber ball on the ground. During the bounce when the ball is in contact with the ground, how does the magnitude of the force of the ball on the ground compare to the magnitude of the force of the ground on the ball?

A book is at rest on a horizontal table. The main forces acting on the book are the normal force from the table and the weight of the book. What is the best description of Newton's third law reaction force to the weight?

Newton's Third Law Part 2 Physics Lessons

Boxes A and B are in contact on a horizontal, frictionless surface (Fig. E4.23). Box A has mass 20.0 kg and box B has mass 5.0 kg. A horizontal force of 250 N is exerted on box A. What is the magnitude of the force that box A exerts on box B? <img src="https://lightcat-files.s3.amazonaws.com/problem_images/9d5af570b3673521-1670515530855.jpg" alt="" /><img class="fr-dib" src="https://lightcat-files.s3.amazonaws.com/problem_images/b8c6607d01fd1346-1678205570245.jpg" style="width: 300px;">

Newton's Third Law of Motion: Action and Reaction

World-class sprinters can accelerate out of the starting blocks with an acceleration that is nearly horizontal and has magnitude 15 m/s2. How much horizontal force must a 55-kg sprinter exert on the starting blocks to produce this acceleration? Which body exerts the force that propels the sprinter: the blocks or the sprinter herself?
