A Car Traveling at 20 km/h speeds up to 60 km/h in 6 seconds. What is its Acceleration in m/s2?

By K Balaji|Updated : November 12th, 2022

Acceleration is 50/27 m/s2

Step 1, Given that

Initial velocity = u = 20 km/h = 20 x 5/18 = 50/9 m/s

Time = t = 6 s

Final velocity = v = 60 km/h = 60 x 5/18 = 50/3 m/s

Step 2, Now we have to find the acceleration

Using the first motion equation

we know that

v = u + at

Substituting all the values

50/3 = 50/9 + a x 6

On solving

a = 50/27 m/s2

Hence the acceleration is 50/27 m/s2

Acceleration

The rate at which a velocity changes in relation to time is referred to as acceleration. Due to the fact that it has both magnitude and direction, it is a vector quantity. The second derivative of position with respect to time is another way to put it.

Types of Acceleration

  1. Uniform acceleration: A straight line moving object is considered to be accelerating uniformly when its speed increases uniformly at regular intervals of time.
  2. Non-uniform acceleration: When an item travels with an increase in velocity at irregular periods of time, non-uniform acceleration happens.
  3. Instantaneous acceleration: Instantaneous acceleration is the acceleration of an item at any given instant in time.

Summary:-

A Car Traveling at 20 km/h speeds up to 60 km/h in 6 seconds. What is its Acceleration in m/s2?

A car traveling at 20 km/h speeds up to 60 km/h in 6 seconds. Its acceleration is 50/27 m/s2
