Question

A car is moving at a speed of 18km/h. It start sretarding uniformly at1m/s² and
come storest. Find the distance travelled.​

Answer 1

Explanation:

Given :-

Initial Velocity u = 18 km/h = 5 m/s

Final Velocity v = 0 m/s ( as car stops)

Acceleration a = - 1 m/s² (retarding)

Distance S = ?

• From third equation of motion

v² = u² + 2aS

0² = 5² + 2 (-1) S

0 = 25 - 2S

S = 25/2

S = 12.5 m
