A Pickup truck with a mass of 1230 kg is moving at 44 m/s and stops in a distance of 33 m. What is direction and size of the
force acting on the truck?

Answer:

-8.025m/s

Explanation:

Because acceleration is negative, it will move in the opposite direction of velocity and the force is 36,080 N.

Velocity and force-based problem:

What information do we have?

Mass of truck = 1230 kg

Velocity of truck = 44 m/s

Distance cover = 33 m

a = (v² - u²) / 2S

a = (0² - 44²) / 2(33)

a = -1,936 / 66

a = - 29.33 m/s²

Force = ma

Force = (1230)(-29.33)

Force = 36,080 N
