Answer to Question #83032 in Physics for Deighl

Question #83032

The velocity of a particle moving along the x-axis varies according to the expression Vx=40-5t^2. Find the average acceleration in the time interval t=0s to t=2s

Expert's answer

Average acceleration

a=Δv/Δt=((40-5×2^2 )-(40-5×0^2))/2=-10 m/s^2
