Question
A car moving at a speed of 40 km/h increases its speed to 60 km/h in 1 hour. The acceleration of the car is______ km/h2.
Hint:
acceleration =∆u-∆v/∆t .
u is initial velocity
v is final velocity.
The correct answer is: 20
Acceleration is defined as change in velocity with change in time.
Here, the car is starting from 40 km/h and goes to 60 km/h in 1 hour of time.
The acceleration of the car is 20 km/h2.
