the speed of the moving car is 72 km/hr . calculate in m/s.
Given that the speed of a car =72 Km/hr
In order to convert it into m/s we have to multiply the value with 5/28
Therefore, we have... 72Km/hr = 72×5/18 = 20 m/s
A car rated at 20kW is moving at 72 km/hr. Calculate the force applied by its engine.
