Question

The position x of a particle moving in a straight line.
varies with time t as x = (t + 3)-1. The acceleration
of particle is proportional to​

Answer 1

Explanation:

x = 1/(t +3)

differentiating wrt t we get

velocity = -1/(t+3)^2

differentiating wrt t we get

acceleration = 1/(t+3)^3

hence acceleration is inversely proportional to

(t+3)^3

Answer 2

Answer:a is inversly proportional to tcube
