18. A car's velocity increases from 10. m/s to 20. m/s in 5.0 s.

What is the acceleration of the car? How much distance does the car cover?

Final answer:

The acceleration of the car is 2.0 m/s² and the distance covered is 75. m.


Step-by-step explanation:

The acceleration of the car can be calculated using the formula:

acceleration = (final velocity - initial velocity) / time

Substituting the given values:

acceleration = (20. m/s - 10. m/s) / 5.0 s = 2.0 m/s²

Therefore, the acceleration of the car is 2.0 m/s².

To calculate the distance covered by the car, we can use the kinematic equation:

distance = initial velocity × time + (1/2) × acceleration × time²

Substituting the given values:

distance = 10. m/s × 5.0 s + (1/2) × 2.0 m/s² × (5.0 s)² = 50. m + 25. m = 75. m

Therefore, the car covers a distance of 75. m.
