The velocity of a car increases from 36 km/h to 108 km/h in 10s. find its acceleration |
|
Answer» Answer: <U>Given :➡️ u = initial VELOCITY = 36km/hrthat is, u = 36×1000/3600 m/sthat is, u = 10m/s➡️v= final velocity = 108km/hrthat is, v= 108×1000/3600m/sthat is, v= 30m/s➡️ time = t = 10sTo find :➡️ ACCELERATION of the carSolution :we know thatacceleration(a) = (v-u)/tthat is, a = (30-10)/10m/s squarethat is, a = 20/10m/s squarethat is , a = 2 m/s squareHence, acceleration of the car is 2 m/s square. |
