Problem 2a

Answer 1

Given information

A box rests on the (frictionless) bed of the truck. The truck driver starts the truck and accelerates forward. The box immediately starts sliding towards the back of the bed of the truck.

 

Step-by-step explanation

Step 1.

Applying Newton's laws of motion here:

Newton's first law: Every person remains in his state of rest or in a state of uniform motion unless he is compelled by an unbalanced external force.

Newton's second law: The force acting on the mass causes the object to move.
