Question

define uniform acceleration and write its SI unit a bus travel the first 20 km in 1 hour next 20 km and half hour and next 20 km in 1 hour calculate the average speed of bus

Answer 1

A body has uniform acceleration if it travels in a straight line and it's velocity increases by equal amount in equal intervals of time. It's SI unit is m/s*s.                                         Average speed =Total distance /total time taken                       =20+20+20/1+1+0.5 km/hr*hr         80/2.5km/hr*hr  =32km/hr*hr
