Question

the displacement x of a particle along a straight line at a time T is given by X is equals to 2 + 3t + 5t^2 the acceleration of particle at t = 2 sec​

Answer 1

Answer: 10 m/s^2

Explanation:

S = 5t^2 + 3t + 2 m

•DIFFERENTIATE w.r.t 't'

V = 10t + 3 m/s

• DIFFERENTIATE w.r.t 't'

A = 10m/s^2 (constant acceleration )

Hope it is helpful ☺
