Question

A car start from rest and attend a speed of 8 m/s in 2 sec it travel former uniform speed for 3 sec calculate average velocity in 5sec​

Answer 1

Explanation:

8m/s in 2 seconds then in 3 seconds it will be 20m/s as the car is moving in uniform speed

The average velocity= displacement / time = 28/5=5.6m/s

Answer 2

Given,

Speed of car=8m/s in 2 seconds

And asked average velocity for 3 seconds in uniform velocity.
So,

Average Velocity =displacement/change in time

Average Velocity =(8m/s)/(3+2)s
=(8m/s)/5s
=8m/5

Therefore Average Velocity of car is 8m/5 (or) 1.6m
