Question

1. What is the average distance travelled by a vehicle moving at a speed of 72 KM per hour in 1 second?
(A).10 m
(B).20 m
(C).16.66 m
(D).33.2m

Answer 1

Answer is (B) 20m...

In an inertial frame of reference, Speed=Distance/time.

Given here, speed= 72km/hour= 72km/3600seconds=72000m/3600seconds

That is, speed=20m/s (International System of Units)

For time= 2 seconds, distance=speed*time (just rearranging the above formula)

Therefore Distance traveled by the car=20*1m=20 meters!

Answer 2

the answer is 20 m
