A car starts from rest and moves at the speed of 30 kph after half an hour.what is the cars acceleration?
(30 km/hr)/(1/2 hr) = 60 km/hr^2
To find the car's acceleration, we need to determine the change in its velocity and the time it took to change that velocity.
Given:
Initial velocity (u) = 0 kph (car starts from rest)
Final velocity (v) = 30 kph
Time (t) = 0.5 hours
We can use the formula for acceleration:
Acceleration (a) = (v - u) / t
Plugging in the values:
Acceleration (a) = (30 kph - 0 kph) / 0.5 hours
Acceleration (a) = 30 kph / 0.5 hours
Acceleration (a) = 60 kph/hour
Therefore, the car's acceleration is 60 kph/hour.
