Question

From rest , a car accelerated at 8 meters per second square for 10 seconds . What is the position of the car at the end of the 10 seconds ?

Answer 1

Answer:

Position of the car at the end of 10 seconds is 400 meters away from the starting point.

Explanation:

Acceleration of car (a) = 8 m/s2

Time (t) = 10 sec

Initial velocity (u) = 0 m/s

s = distance covered

s = ut + 1/2 at2

s = 0 + 1/2* 8*100

s = 800/2

s = 400 metres

Answer 2

Answer:

Position of the car at the end of 10 seconds is 400 meters away from the starting point.

Explanation:

Automatic speed (a) = 8 m / s2

Time (t) = 10 seconds

Initial speed (h) = 0 m / s

s = distance traveled

s = ut + 1/2 ug2

s = 0 + 1/2 * 8 * 100

s = 800/2

s = 400 meters
