A race car accelerates uniformly from 19.5 m/s to 50.1 m/s in 2.47 seconds. Determine the acceleration of the car and the distance traveled.

12.4m/s²; 80.99m

Explanation:

Acceleration can be defined as the rate of change of the velocity of an object with respect to time.

This simply means that, acceleration is given by the subtraction of initial velocity from the final velocity all over time. Hence, if we subtract the initial velocity from the final velocity and divide that by the time, we can calculate an object’s acceleration.

Mathematically, acceleration is given by the equation;

Given the following data;

Initial velocity = 19.5m/s

Final velocity = 50.1m/s

Time = 2.47 secs

Substituting into the equation;

Acceleration, a = 12.4m/s²

Solving for the distance covered;

Substituting into the values into the equation;

S = 80.99m

conduction, convection, radiation

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
