A body travels from A to B with a velocity of 90 km/h and return to A with a velocity of 60 km/h . What isthe average velocity and average speed? |

Answer» AVERAGE SPEED=> Initial speed from a to b = 60km/h DISTANCE = 60kms. Final speed form b to a = 90km/h Distance = 90kms. ➡Average speed = Total distance / total time taken ➡Average speed = 60 +90 /1 + 1 ➡Average speed = 60 + 90 / 2 ➡Average speed = 150 / 2 ➡Average speed = 75km/h. AVERAGE VELOCITY Initial velocity (U) = 60km/h Final velocity (v) = 90km/h ➡Average velocity = v + u / 2 ➡Average velocity = 90 + 60 / 2 ➡Average velocity = 150 / 2 ➡Average velocity = 75km/h please mark me brain mark list |
