Did you know?
Did you know that the acceleration, retardation, and total distance covered by a car can be calculated using information about its speed and time? In this scenario, the car accelerates for 10 seconds to reach a speed of 20 meters per second. It then maintains a constant speed for 20 seconds before decelerating to a stop in 20 seconds. To find the acceleration, we divide the change in velocity (20 m/s - 0 m/s) by the time taken (10 seconds), resulting in an acceleration of 2 meters per second squared. The retardation can be calculated similarly by dividing the change in velocity (0 m/s - 20 m/s) by the time taken (20 seconds), which gives us a retardation of -1 meter per second squared. Finally, to determine the total distance covered, we add the distances covered during each phase. The distance covered during acceleration can be computed using the formula distance = initial velocity × time + 0.5 × acceleration × time squared. The distance covered during the constant speed phase is simply the product of the speed and time. The distance covered during deceleration is calculated using the same formula as acceleration but with the negative value for retardation. By calculating these distances and summing them up, we can find the total distance covered by the car.
