The function x(t)=-2.73e^(1.23t)?

Question

Update : The function x(t)=-2.73e^(1.23t) describes the position, in meters, of a particle on the x-axis as a function of time t, in seconds. Find the particle\'s velocity at time t = 3.05 s.

Answer 1

x(t)=-2.73e^(1.23t)

Velocity of particle can be defined as the rate of change in the position with respect to time 

velocity v(t) = at t = 3.05sec

Velocity of particle is -142.995 m/s
