3. A moving car covers a distance of 100 km in two hours. What is meant by this?

GenaCL600 [577]

Answer:

50km /hour

Explanation:

The car moves 100km in two hours.

We can write a ratio like this:

100km : 2hr

Divide both sides by two and you get:

50km : 1hr

Meaning the moving car is moving 50km an hour.

Hope this helps :)

A car traveling initially at 7.35 m/s acceler-

Flura [38]

Answer:

$v_f=9,07~m/s$

Explanation:

Constant Acceleration Motion

It's a type of motion in which the velocity of an object changes uniformly in time.

Being a the constant acceleration, vo the initial speed, vf the final speed, and t the time, the following relation applies:

$v_f=v_o+at$

The car initially travels at vo=7.35 m/s and accelerates at a rate of $a=0.824~m/s^2$ during t=2.09 s.

The final velocity is:

$v_f=7.35+0.824*2.09$

$\mathbf{v_f=9,07~m/s}$
