A car is moving at a rate of 72km/hr. How far does the bus move when it stops after 4 seconds?
Let the velocity of the car be “v = 72km/hr = 20m/s”. By definition, the velocity is:
“v = dfrac{d}{t}”
where “d” is the distance covered in “t = 4s”. THus, obtain:
“d = vt = 20m/scdot 4s = 80m”
Answer. 80 m.
