Question

Pickup trucks and SUVs need up to __________ more distance to stop than passenger cars.

Answer 1

Answer:

20%

Explanation:

Any object which is moving has kinetic energy. Kinetic energy is given by

$K=\dfrac{1}{2}mv^2$

Where,

m = Mass of object

v = Velocity of object

A heavier object will have more kinetic energy. An SUV is heavier that a normal car so the kinetic energy that the brakes have to dissipate will be higher taking longer to stop. Hence, an SUV will stop after a longer distance.
