1. A bus starts from rest and attains 40 kmhin (1) km h-2 and (ii) ms?velocity after 10 seconds. Calculate the acceleration of the busAns.( 14400 km2

Answer»

We know,v = u + at

v = final velocityu = initial velocitya = accelerationt = time

t = 10 sec = 10/3600 hr

40 = 0 + a*(1/360)

a = 40*360 = 14400 km/hr^2

In m/s^2a = 14400 * 1000/(3600*3600) = 14400 * (1/18*720) = 1.11 m/s^2
