A car starts from rest and moves with a uniform acceleration of 30ms-2 for 20s. Calculate the distance covered at the end of the motion

Answer Details

The distance covered at the end of the motion is 600 meters.
The distance covered by an object with uniform acceleration can be calculated using the equation:
distance = initial velocity x time + (1/2) x acceleration x time^2
In this case, the initial velocity is 0 (the car starts from rest), the acceleration is 30 m/s^2, and the time is 20 seconds. Plugging in these values, we get:
distance = 0 x 20 + (1/2) x 30 x 20^2
distance = 0 + (1/2) x 30 x 400
distance = 600 meters
So, the car covers a distance of 600 meters at the end of the 20 seconds of motion.
