Explain the interaction between centripetal force and inertia and what kind of motion this interaction causes.

Hatshy [7]

Centripital force is a force that draws an object toward a center point. Think of gravity acting on a celestial object as it revolves around the sun, or the force that a string exerts on a ball tied at the end of it to keep it from flying away.
Inertia is the forward momentum of an object, the tendency of an object to continue moving in the direction it is already moving in.
Intertia and centripital motion combine to create circular motion, as an object that is moving in some direction away from a center object, but still drawn to that object by a centripital force, will continue to move, at the same distance away from the object, in a circle around it.

An elevator accelerates upwards at an acceleration of 2 m/s. The mass of the elevator is 3500 kg. What is the tension in the ele

yawa3891 [41]

Answer:

B) 41,335 N

Explanation:

As the elevator moves upward the formula for the calculation of tension in the cable is given by.

T-mg =ma

T=mg+ma

T=3500*9.81+3500*2

=34335+7000

T=41,335 N

George's speed per second is 76.92 m/s

George's velocity in meters per second was 38.46 m/s (North)

<u>Explanation:</u>

When dividing the total distance covered by object by time, we get the value for average speed.

$\text { speed }=\frac{\text {distance}}{\text {time}}$

<u>Given:</u>

t = 13 seconds

Calculate the distance without consideration of motion’s direction. So, the distance walks 750 m north first, and then turn around walks 250 m south, so the total distance covered is

d = 750 + 250 = 1000 meters

To find the rate per second, simply divide the distance by the time.

$\text { speed }=\frac{1000}{13}=76.92 \mathrm{m} / \mathrm{s}$

In given case, the students walks 750 m north first, and then turn around walk 250 m south. The displacement is the distance in a straight line between the initial and final position: therefore, in this case, the displacement is

d = 750 (north) - 250 (south) = 500 m (north)

The time taken is t = 13 s

So, the average velocity is $\text {velocity}=\frac{500}{13}=38.46 \mathrm{m} / \mathrm{s}$ (North)

And the direction is north (the same as the displacement).
