1. A scooter acquires a velocity of 36km/h in 10 seconds just after the start. Calculate the acceleration of the scooter. |

Answer» -Given:INITIAL Velocity (u) = 0 m/s ( the scooter starts from rest)Final Velocity (V) = 36 km/h1 km/h = 5/18 m/s→ v = 36 * 5/18→ v = 10 m/sTime TAKEN (t) = 10 sWe know that,acceleration (a) = (v - u) / t→ a = (10 - 0) / 10→ a = 10/10→ a = 1 m/s²Therefore, the acceleration of the scooter is 1 m/s².Additional Information:-Acceleration:Acceleration is the rate of change of Velocity with respect to time.a = Final velocity - initial Velocity/timeIt's S.I unit is m/s² and C.G.S unit is cm/s².It is a vector QUANTITY (has both DIRECTION and magnitude).It depends on two physical quantities Velocity, time. |
