Answer:

The ground pushes back on your feet with equal force

Explanation:

When you walk across the ground and push on it with your feet, the ground pushes back on your feet with an equal and opposite force.

This interpretation and knowledge is gotten from Newton's third law of motion.

It states that "action and reaction force are equal and opposite in nature".

The force applied to a body responds with an opposite force in the other direction.
Therefore, the reaction force is of equal magnitude but directed in another direction.

A flywheel flows from 250rpm to 150rpm in 4.2 seconds. How many revolutions occur during this time

Assoli18 [71]

Answer:

7revolutions

Explanation:

Given parameters:

Initial revolution = 250rpm

Final revolution = 150rpm

Time = 4.2s

Unknown:

Number of revolutions that occur at this time = ?

Solution:

To solve this problem;

let us find the change in revolution = 250rpm - 150rpm = 100rpm

Convert the time to seconds;

60s makes 1 minute

4.2s will make $\frac{4.2}{60}$ = 0.07min

So;

The number of revolutions at this time = 100rpm x 0.07min

= 7revolutions

a=1.4 m/s²

V²=v0²+2a.D

28²=0+2x1.4D

784 = 2.8D

D = 280 m
