Question

If the position of a body
is x= 3t+ 5t² then find
the average
velocity?​

Answer 1

Explanation:

Given displacement x=5+3t+2t2

Differentiating the above equation with respect to time t we get velocity of the body

v=dtdx=3+4t 

Now again differentiating the velocity with respect to time we get acceleration 

a=dtdv=4
