The distance covered by a body along the x axis is given by x=2t^3+5t^2+t where t is measured in seconds and x is in meter. Find average speed in a time interval from t= 0s and t=2s

Explanation:

It is given that,

The distance covered by a body along the x-axis is given by :

t is in seconds and x is meters

Speed of the body is given by :

At t = 0,

At t = 2 s,

So, the average speed in a time interval from t= 0s and t=2s is 45 m/s.
