A runner accelerates at 1.2 m/s? with a force of 92.4 N. What is the runner's mass?

Analyzing Forces: Using Newton's 2nd Law A fireman has a mass of 75 kg. When the bell in the firehouse starts ringing, he slides down the pole with an acceleration of 3 m/s². What is the total force of friction acting on his body? 1. Identify the problem: What quantity are you being asked to find? What units will this answer be in? 2. Visualize and then sketch the problem. Draw arrows to illustrate the direction of the two forces acting on the fireman. Label these two forces by name. Do not use numbers yet. 3. These two forces act in opposite (+/-) directions and they will partially cancel. Assign the + value to the stronger force. The sum of these two forces is called the Net Force and it is the force which will actually move the fireman. Fill in the names of these two forces in the equation template below. (Hint: Remember that mass and weight are not the same.) Do not use numerical values yet: Net Force = + 4. Newton's 2nd Law gives us another equation for calculating Net Force: Net…

Free Response Questions ou push a grocery cart at an angle, down and to the left. The cart accelerates along a level floor in the prestince of friction effects between the cart and the floor. Draw force diagrams for you, the cart, and the floor/earth. Fully label all vectors. a. you floor/Earth cart b. While you are making the cart speed up, how does the size of the force you apply on the cart compare to the size of the force the cart exerts on you? Explain by referencing Newton's Laws c. While you are making the cart speed up, how does the size of the frictional force on the cart by the floor compare to the force applied on cart by you? Explain by referencing Newton's Laws While you are making the cart speed up, how does the size of the frictional force on the cart by the floor compare to the frictional force on you by the floor? Explain by referencing Newton's Laws Identify & list all of the Newton's Third Law pairs in your force diagrams.

What is a, in m/s ? 500 kg frictionless, massless pulleys = 0.2 400 kg

Select all the examples that are scalar quantities. speed acceleration force displacement mass distance velocity

Is this correct?

Describe how a car moving at a constant speed can still be accelerating. Use the definitions of terms from the lesson in your answer.

Inertia by definition is the propter of things to resist changes in motion. This quantity is directly related to an object’s mass, or how much of ‘something’ and object is made of. Therefore, could Inertia change if your object were to travel into space? Could it change if your object was on the moon? If not, explain how you could change an object’s inertia.

Hi, good day can you give me a brief explanation of Vector Addition of Forces and an example?
