Step 1
To find the velocity at t=20 sec, we can substitute t=20 into the given v-t curve equation: v = -4 + 80t v = -4 + 80(20) v = -4 + 1600 v = 1596 m/s Show more…

The velocity of a car is plotted as shown. Determine the total distance the car moves until it stops $(t=80 \mathrm{~s})$. Construct the $a-t$ graph.
The car in moves in a straight line such that for a short time its velocity is defined by v = f(t) =(3t^2 + 2t) m/s where t is in second. When t = 0, s = 0. Determine it position (s) and acceleration (a) when t = 3s.
