32 kmph = 8.889 m/s
72 kmph = 20 m/s
Acceleration = (v^2 - u^2) / (2S)
= (20^2 - 8.889^2) / (2 × 50)
= 3.20 m/s^2
Time taken = (v - u) / a
= (20 - 8.889) / 3.20
= 3.47 seconds
72 kmph = 20 m/s
Acceleration = (v^2 - u^2) / (2S)
= (20^2 - 8.889^2) / (2 × 50)
= 3.20 m/s^2
Time taken = (v - u) / a
= (20 - 8.889) / 3.20
= 3.47 seconds
