. A bus starts from rest and attains a speed of 36kmh^-1 in 1 minute while moving with uniform acceleration along a straight road. Calculate the acceleration of the bus.​

Answer»

eration = 0.17 m/s² ✬ Explanation: Given: A bus stars from rest (u) = 0 Bus attains speed (V) of 36 km/h. Time (t) taken to attain 36 km/h is 1 MINUTE. To FIND: What is the acceleration (a) of the bus ?. Formula to be used: First LAW of motion v = u + at Solution: Here, final velocity (v) is in km/h so we need to CHANGE it in m/s. ➨ 36 km/h = 36  5/18 m/s ➨ ( 2  5 ) m/s ➨ 10 m/s ( Final Velocity ) Changing time into seconds ➨ 1 minute = 60 seconds Now, put the values on formula v = u + at 10 = 0 + a  60 10 = 60a 10/60 = a 0.166 m/s² or 0.17 m/s² = a
