Question

Abbas accelerated uniformly from 54km/hr to 72km/hr in 10 seconds find the acceleration and distance covered by bus in metre

Answer 1

u=54 km/h = 15 m/s
v=72 km/h = 20 m/s
t=10 seconds
acceleration =?

acceleration=v-u/t
acceleration=20-15/10
acceleration=0.5m/s


S=ut+1/2*at^2
S=15*10+1/2*0.5*10^2
S=150+0.5*50
S=150+25
S=175 meters
