Question

If the relation between acceleration and time for an object is given by
a = 2t + 4t2
Calculate the position of object from the origin at t = 4 s. (At t = 0, V = 0.x=0
​

Answer 1

Answer: x=298.6 m

Explanation:

For this you should apply integration method.

You will get,

x= 2t^3 /3 + t^4

Put t=4,

x=298.6 m
