A motor bike, initially moving at 18 km/h, accelerates at a rate of 5 m/s2 and the distance covered by it from start is 87.5 m. Calculate the final velocity?
Step-1:Given data:
Acceleration(a)=5
Distance(s)=87.5 m
Initial velocity=
Step 2:Formula used
where v is the final velocity, u is the initial velocity, a is the acceleration and s is the distance covered.
Step-3: Finding the final velocity
As we know:
Hence, the final velocity is 30 .
