I see, thanks. after putting the unit it makes more sense now

Distance: substitute t=5 into x=3e^(0.4t) 22.17m Velocity: v=dx/dt =1.2e^0.4t____(1) Sub t=5 back into (1) v= 8.867m/s Acceleration: a=dV/dt =0.48e^0.4t____(2) sub t=5 back into (2) a= 3.547 m2/s I am not sure if i am doing this right on dx/dt and dv/dt
