Identify the type of motion for each number

1 answer:

6 0

A :-) 1.) 3rd law of motion.

2.) 2nd law of motion ( law of inertia ).
- 2nd law states that if an object has more mass then it has more inertia ( mass = inertia ).
So , here the empty shopping cart is easier to push compared to loaded one.

3.) 1st law of motion.
- 1st law states that a object in rest will stay at rest , if a object is in motion it will stay at motion until a unbalanced force is applied on it.
So , here the baseball was in motion then , an unbalanced force ( bat ) was applied on it , so the was thrown up into the air.

4.) 3rd law of motion.
- 3rd law states that every action force has an equal and opposite reaction force.
So , here when your walking , your foot pushes the ground backwards ( action force ) , and the ground pushes your foot forward ( reaction force ).

5.) 1st law of motion.

A skier is standing on a horizontal patch of snow. She is holding onto a horizontal tow rope, which is about to pull her forward

The magnitude of the maximum force that the tow rope can apply to the skier without causing her to move will be 81.03 N,

<h3>What is the friction force?</h3>

It is a type of opposition force acting on the surface of the body that tries to oppose the motion of the body. its unit is Newton (N).

It is defined as the product of the coefficient of friction and normal reaction.

On resolving the given force and acceleration. Mathematically aion in the different components and balancing the equation gets. Components in the x-direction.

The normal force is balanced by weight;

N = mg

The magnitude of the maximum force that the tow rope can apply to the skier without causing her to move is;

F = μN

F= μmg

F=0.14 × 59 kg × 9.81 m/s²

F = 81.03 N

Hence, the magnitude of the maximum force will be 81.03 N,
