A car starts from rest and moves at the speed of 30 kph after half an hour. What is the cars acceleration?

clearly, it is

(30km/hr)/(1/2 hr) = 60 km/hr^2

To find the car's acceleration, we need to use the formula for acceleration:

Acceleration = (Final Velocity - Initial Velocity) / Time

In this case, the initial velocity is 0 kph (since the car starts from rest), the final velocity is 30 kph, and the time is 0.5 hours (since it took half an hour for the car to reach this speed).

Let's plug these values into the formula:

Acceleration = (30 kph - 0 kph) / 0.5 hours

Simplifying the equation, we have:

Acceleration = 30 kph / 0.5 hours

Now, we divide 30 kph by 0.5 hours:

Acceleration = 60 kph/h

Therefore, the car's acceleration is 60 kilometers per hour per hour (kph/h).
