Given:

Initial velocity (u) = 18 km/h

Final velocity (v) = 36 km/h

Time (t) = 5 minutes = 5/60 hours = 1/12 hours

To find:

Acceleration (a)

Solution:

We know that acceleration (a) is given by the formula:

a = (v - u) / t

Substituting the given values:

a = (36 - 18) / (1/12)

a = 18 / (1/12)

a = 216 km/h^2

Therefore, the acceleration of the car is 216 km/h^2.

Explanation:

When a car accelerates uniformly, it means that it is changing its velocity at a constant rate. The acceleration is the rate at which the velocity of the car changes. In this case, the car starts from a velocity of 18 km/h and reaches a velocity of 36 km/h in a time of 5 minutes. To find the acceleration, we use the formula a = (v - u) / t, where v is the final velocity, u is the initial velocity, and t is the time taken. We substitute the given values and solve the equation to get the acceleration. The unit of acceleration is km/h^2, which means that the velocity changes by km/h per hour.

A={(36×5/18)-(18×5/18)}/5×60 m/s^2


=1/60 m/s^2
