Question

A car travels first 60 km of a distance in 1 hr, next 70 km of the distance in next hour and remaining 20 km distance in final hour. Then, its motion is:
  1. uniform motion
  2. non-uniform motion
  3. either uniform or non-uniform motion
  4. neither uniform nor non-uniform motion

A
uniform motion
B
non-uniform motion
C
either uniform or non-uniform motion
D
neither uniform nor non-uniform motion
Solution
Verified by Toppr

During first hour, speed = 601 km/h=60 km/hr
During second hour, speed = 701 km/h=70 km/hr
During third hour, speed = 201 km/h=20 km/hr
So, the car travels different distances in equal time intervals. This is an example of non-uniform motion.
