Question

A car is travelling with a speed of 36km/hr increases its speed to 108 km/hr with a uniform acceleration of 4m/s^2. Distance travelled by the car to acquire this speed is ?

Answer:

Given , Initial speed , u = 36 km/h

Final speed , v = 108 km/h

Acceleration = 4 m/s²

Distance , s = ?

From 3rd equation of motion ,

v² - u² = 2as

=> (108)² - (36)² = 2(4)s

=> 8 s = 10368

=> s = 1296 m

Hence Distance traveled by the car to acquire this speed is 1296 meters.
