A car starts from x=10 m at t = 0 and moves with the velocity graph shown in figure below. What is the object's position at 3.4 s?
Equation for v-t graph:
v/40 + t/4 = 1
=> v = -10t + 40
=> dx/dt = -10t + 40
=> 10∫x dx = 0∫t (-10t + 40)dt
=> x - 10 = -5t2 + 40t
=> x = -5t2 + 40t + 10
At t = 3.4 s, x = -5(3.4)2 + 40(3.4) + 10 = 88.2 m
