Question

A motor car is travelling at 36 km/hr After 10 sec , the
velocity becomes 54 km/hr Assuming the velocity change took place
at auniform rate, find the acceleration

Saurabh Gupta · Accepted Answer

u=36km/h=36*5/18=10m/s
v=54km/h=54*5/18=15m/s
t=10sec
So a=Change in velocity/Time taken=(15m/s-10m/s)/10sec
=(5m/s)10sec =0 5m/s2

A motor car is travelling at 36 km/hr.After 10 sec., the velocity becomes 54 km/hr.Assuming the velocity change took place at auniform rate, find the acceleration.
