Abicycle, a motorcycle, a sports car, and a pickup truck are traveling at the same velocity. which vehicle requires the greatest amount of force to change its velocity?
a. a bicycle
b. a motorcycle
c. a sports car
d. a pick-up truck

D.a pick-up truck

Explanation:

Force required to move an object is given by

F = ma

Where,

m = Mass

a = Acceleration

Here, the acceleration is constant as all the velocities are same so the mass varies the force required. From the equation it can be seen that force varies directly with mass i.e., if mass increased the force will also be increase.

Out of the options here the pick up truck has the most mass so the amount of force will be greatest here.

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.

it breaks and dirupture other materials and other sencews from the bottom
