Question

the displacement of a body from reference point is given by root x= 2t+3 where x is in meter and t is in sec what is acceleration of body ​

Answer 1

acceleration=8ms^-2.

Explanation:

x^1/2 =4t^2+9

differentiating the abobe equation 2 times will gives tha equation of acceleration in terms of t and X.

a =( dx/ dt)^2 = 8

I hope it help u... byeeeeee
