Answer:
Approximately .
Explanation:
Assuming that there is no other force on this vehicle, the force from the road would be the only force on this vehicle. The net force would then be equal to this
force. The size of the net force would be
.
Let denote the mass of this vehicle and let
denote the net force on this vehicle.
By Newton's Second Law of motion, the acceleration of this vehicle would be proportional to the net force on this vehicle. In other words, the acceleration of this vehicle, , would be:
.
For this vehicle, whereas
. The acceleration of this vehicle would be:
.
Least count of the pulse stopwatch is given by
this means each division of the stopwatch will measure 0.1 s of time
After 3 journeys from one end to other we can see that total time that is measured here is shown by the clock as 52nd division
So here total time is given as
Time = (Number of division) (Least count)
now we will have
