Question

A vehicle moves in a straight line with an acceleration of 4 km/h2. By how much does the speed change each second? Answer in units of km/h.

Answer 1

Answer:

The speed of the vehicle changes in each second is, v = 0.00111 Km/h

Explanation:

Given,

The acceleration of the vehicle, a = 4 Km/h²

Converting it into m/s,

                                                    a = 0.0003086 m/s²

In each second the vehicle covers 0.0003086 m

The speed of the vehicle in each second is given by 0.0003086 m/s

Converting it into Km/h

                                     v = 0.00111 Km/h

Therefore, the speed of the vehicle changes in each second is, v = 0.00111 Km/h
