The correct answer is B. The pickup truck is moving at 4 m/s and the school bus is moving at 2 m/s.

Explanation:

The kinetic energy is related to how fast a body moves (speed), as well as, the amount of matter in the object (mass). Due to this, even if the bus and the truck move at the same speed they do not have the same kinetic energy. Indeed, the graph shows in general the kinetic energy is higher for the school bus.

However, this does not occur if the truck moves at 4 m/s and the bus moves at 2m/s because, at this speed, the kinetic energy of the truck is 30 kilojoules, while the kinetic energy of the bus is around 15 kilojoules, which is lower. According to this, the correct answer is B.

<span>·         </span>Ordinary Americans inspired New Deal because of these aspects; they created jobs and the unemployment dropped from 25% to 14%, they also restored confidence in the banking system. They Gave people hope with his confidence and his fireside chats and created agencies that have prevented another Depression (FDIC, Social Security).

<span>·         </span>The reason why their progress is hinder is because of negative aspect like; the raised taxes to pay for programs, deficit spending - country went into debt and some of his programs (AAA, NIRA) declared unconstitutional.  The New Deal did not end the Depression - preparing for WW2 did.  Minorities left out of many ND programs.
