Given :-
Initial velocity of car is 0 m/s
Final velocity of car is 20 m/s
Distance covered by car is 100m
To Find :-
Acceleration of car
Solution :-
❍ We can find the acceleration by putting the values in the third equation of motion ::
v² = u² + 2as
Where,
- v denotes final velocity
- u denotes initial velocity
- a denotes acceleration
- s denotes distance covered
⠀⠀⠀⠀⠀━━━━━━━━━━━━━━━━━━━⠀
Finding Acceleration :-
=> ( 20 )² = ( 0 )² + ( 2 × a × 100 )
=> 400 = 0 + 200a
=> 200a = 400 - 0
=> 200a = 400
=> a = 400/200
=> a = 2m/s²
⠀⠀⠀⠀⠀━━━━━━━━━━━━━━━━━━━⠀
- Henceforth, acceleration of car is 2m/s²
