There are four forces acting on a car. The forces are:
Elenna [48]

Answer:

<em>| Fn | = 258 N</em>

Explanation:

<u>Net Force</u>

The net force vector is the sum of all the force vectors applied to a body.

There are four forces applied to a car:

325N to the north

175N to the south

465N to the east

255N to the west

To simplify the calculations, we find the net force by each axis separately, considering forces to the right and upward as positive.

Fx = 465 N - 255 N = 210 N

Fy = 325 N - 175 N = 150 N

The magnitude of the net force is:

|Fn|=\sqrt{210^2+150^2}

|Fn|=\sqrt{44100+22500}

|Fn|=\sqrt{66600}

| Fn | = 258 N

At what speed does a clock move if it is measured to run at a rate two-fifths the rate of a clock at rest with respect to an obs
Liono4ka [1.6K]

Answer:

0.44c

Explanation:

We know that

Time interval at speed (ts)= time interval at rest(tr) / gamma

where

gamma = √[1-(v/c)²]

ts = tr / gamma

tr/ts = gamma

But

Ss/Sr = gamma

Where

Sr = clock speed at rest, Ss at speed):

So

√[1-(v/c)²] = 2/5

1 - (v/c)² = 4/25

(v/c)²= 5/25

v/c = √5 / 5

v = 0.444c
