Question

What average force is required to accelerate a 5.0 kg block from rest to a final speed of 54.0 m/s
in 9.0 seconds?

Answer 1

See the post above..

Formula used:-

Force=Mass×acceleration

Answer 2

Answer: The answer to this question is-

We know that-

$V_{f}$ = $V_{i}$ + at

Given-

       $V_{f}$ = 54m/s

       t = 9 seconds

       $V_{i}$ = 0

Hence-  54 = 0 + a × 9

            ⇒ a = 6 m/$s^{2}$

∴ F = ma

⇒ F = 5 × 6

⇒ F = 30 N

Explanation:

Motion is described in physics as a change in position with respect to time. Motion, to put it simply, is the movement of a body. Motion is typically characterised as:

1.Variation in speed

2.Change of course

Here are a some of the consequences that the Force can have.

• A body at rest can be forced to move.

• It can either slow down or stop a moving body.

• It can quicken the pace of a moving object.

• Along altering its size and shape, it can alter the direction of a moving body as well.
