Question

A car acceleration uniform from 18 km/h to 36 km/h in 5 second . calculate :- the acceleration

Answer 1

Intial velocity,u = 18km/hr , multiply this with 5/18 for this is the coneversion factor. therefore you get 5m/s

Final velocity,v = 36km/hr , 10m/s
Time = 5sec
we know,
acceleration= v-u/t
10 - 5/5
1m/s
Therefore the acceleration is 1m/s
