Answer to Question #138928 in Physics for Hannah

Question

Q2) A truck driver, reacting quickly to an emergency, applies the brakes. During the driver’s 0.32 s reaction time, the
truck maintains a constant velocity of 27 m/s [fwd]. What is the displacement of the truck during the time the driver
takes to react?

Answer 1

We can find the displacement of the truck from the formula:

$$s = vt=27\ \dfrac{m}{s}\ [fwd]\cdot 0.32\ s = 8.64 \ m \ [fwd].$$

Answer:

$s =8.64 \ m \ [fwd].$
