Physics 180A Final Exam |True or False| Exam Elaboration [Graded A+] A large crate is at rest on a horizontal floor. A person exerts a horizontal force on the box, but the crate remains at rest. Therefore, the force exerted by the person on the crate and the force of static friction that the floor exerted on the crate form an action reaction pair. *Ans* False If an object of mass 50kg is traveling with a constant velocity of magnitude 10m/s then the net force on this object must be z...

AP Physics Unit 1 Progress Check MCQ Rock X is released from rest at the top of a cliff that is on Earth. A short time later, Rock Y is released from rest from the same location as Rock X. Both rocks fall for several seconds before landing on the ground directly below the cliff. Frictional forces are considered to be negligible. Which of the following graphs best represents the vertical displacement of Rock X as a function of time starting from immediately after the rock is released from rest? T...

An amusement park game consists of throwing a quarter into a small bowl. If you win, you get to take home a giant purple stuffed elephant. The dish is on a shelf that is 0.4 m above the point where the quarter leaves your hand. The horizontal distance between the bowl and the place where the quarter leaves your hand is 1.8 m. Ignoring air drag, if you toss the quarter at an angle of 60°, what initial velocity is needed to bring home the giant purple stuffed elephant? correct answers 4.8 m / s ...
