Answer:
The acceleration of a car would be: 
m/s²
Explanation:
Given
Initial velocity = 
m/s
Final velocity = 
m/s
Time elapsed = 
s
To determine
We need to determine the acceleration of a car.
We know that acceleration is basically the rate of change in velocity over time.
Thus,
We can determine the acceleration using the formula
where
is the acceleration
is the initial velocity
is the final velocity
is time elapsed
now substituting the values , , and in the formula
m/s²
Therefore, the acceleration of a car would be: m/s²
Answer:
1. The reason why a plane mirror forms a virtual image is because it doesn't let the light go through it, but it reflects the light, so if you go behind the plane mirror, then you won't see the rays of light since it's not letting the rays of light go behind it.
2. The image cannot be projected onto a screen also.
3. Also, the Rays of light never meet at a focus point, so hence, this is why the plane mirror forms a virtual image.
Thanks!
Since the initial and the final velocity are just equal, it is implied that the acceleration is zero. This means that the net force acting on the body is also zero. The horizontal force should be equal to the force of friction. The force of friction is equal to the product of the coefficient and the normal force.
Ff = (coefficient of friction) x Fn
The normal force is equal to the object's weight if the surface is horizontal.
Ff = (0.20) x (30 kg) x (9.8 m/s²) = 58.8 N

<span>Thus, the horizontal force exerted must be 58.8 N.
