Given:-
- Initial velocity,u = 10 m/s
- Final velocity,v = 0 m/s
- Acceleration,a = -0.5 m/s² [ retardation ]
To be calculated:-
Calculate the distance covered by scooter before it stops ?
Formula used:-
v² = u² + 2as
Solution:-
From third equation of motion,we have
v² = u² + 2as
★ Substituting the values in the above formula,we get :
⇒ ( 0 )² = ( 10 )² + 2 × -0.5 × s
⇒ 0 = 100 + 2 × - 5/10 × s
⇒ 0 = 100 - 1s
⇒ s = 100 m
Hence,the distance covered by scooter is 100 m.
