The car stationary in front of a red traffic light. As the light turns green , a truck goes past at a constant velocity of 1.5 m/s. At the same moment , the car begins to accelerate at 1.25 m/s 2 . When it reaches 2.5 m/s the car continues at this velocity . When does the car pass the truck ? How far they gone from the traffic light at that time ? 25 s / 0.38 km

Answer 1

(1/2)(1.25)(2^2) + 2.5(t-2) = 1.5t
t = 2.5

2.5*1.5 = 3.75

If the 25s/0.38km is supposed to be the answer, I suspect the units have gotten garbled.
