Total distance divided by total elapsed time gives what quantity?

ki77a [65]

<h2>Total distance divided by total elapsed time gives : Average speed </h2>

Explanation:

Speed

It is the distance traveled by body with respect to time .

Its formula is Speed = distance /time

V=S/T

units : m/sec or Km/hr

Distance

It is total path traveled by body in any direction .

It unit and symbol is : S and unit = m /Km

Average speed

It is the total distance traveled by body with respect to total time taken to travel that given distance .

Average speed = total distance /total time

A.s = T.D/T.T

unit = m/sec or Km/hr

Instantaneous velocity

It is the distance traveled by body at particular instant of time ,in given direction .

Displacement

It is the shortest path traveled by body in given direction .

Mrs. Jacobson is pushing a fridge to the right with a force of 100 N. The force pushing it

alex41 [277]

Answer:

Explanation:

Let's illustrate this; see the attachment.

We see that Mrs. Jacobson is pushing to the right with a force of 100 N and there is another opposite force pushing with a force of 15 N. Since these are in opposite directions, we can say that the force opposite to Mrs. Jacobson is pushing the fridge -15 N to the right (instead of 15 N to the left).

The net force would then be:

100 N + (-15 N) = 85 N to the right

The answer is A.
