Question

find the velocity of the particle at initial time x=3t²+5t plzz give me a perfect solution tomorrow is my paper​

Answer 1

Answer:

velocity=dx/dt=6t+5

put t=0

velocity =5 m/s

Answer 2

differentiating the equation with respect to t ,

dx/dt=6t+5

since, v= dx/dt

so, v= 6t+5

initial time means t=0

so, v= 5 m/s
