The object is not moving.

My explanation is that say if you sit a ball on the table and it is a smooth surface with no bumps or anything. The ball will sit still since it can’t roll unless you hit it.

Hope this helps!

Answer:

Acceleration of the car is $1.43\ m/s^2$ .

Explanation:

It is given that,

Initial speed of the car, u = 29 m/s

Finally it reaches a speed of, v = 34 m/s

Distance, d = 110 m

We need to find the acceleration of the car as it speed up. It can be calculated using third law of motion as :

$v^2-u^2=2ad$

$a=\dfrac{v^2-u^2}{2d}$

$a=\dfrac{(34)^2-(29)^2}{2\times 110}$

$a=1.43\ m/s^2$

So, the acceleration of the car as it speeds up is $1.43\ m/s^2$ . Hence, this is the required solution.

Why can we see a red shirt

natita [175]

The colours we see are the wavelengths that are reflected or transmitted. For example, a red shirt looks red because the dye molecules in the fabric have absorbed the wavelengths of light from the violet/blue end of the spectrum.
