Suppose you stand on the floor of a train moving at constant speed in a straight line. If you jump straight upward, you will land
(a) at your original location
(b) slightly in front of your original location.
(c) slightly in back of your original location.
(d) in back of your original location a distance that depends on how high you jump.
The correct option for the statement "Suppose you stand on the floor of a train moving at constant speed in a straight line. If you jump straight upward, you will land".
Answer to Problem 10RAT
The correct option for the statement "Suppose you stand on the floor of a train moving at constant speed in a straight line. If you jump straight upward, you will land" is option (a).
Explanation of Solution
The relative speed is defined as the speed of an object concerning the other moving or fixed object. If two objects were moving in the same direction and with the same speed, then its relative speed is zero.
If a person is standing on the floor of a train moving at a constant speed in a straight line, then the relative speed of you and train is zero. Therefore, if a person jumps straight upward, you will land at your original place because of relative speed. From this, it is concluded that option (a) will be correct in the given options.
Conclusion:
Therefore, the correct option for the statement "Suppose you stand on the floor of a train moving at constant speed in a straight line. If you jump straight upward, you will land" is option (a).

- m C A block of mass m slides down a ramp of height hand collides with an identical block that is initially at rest. The two blocks stick together and travel around a loop of radius R without losing contact with the track. Point A is at the top of the loop, point B is at the end of a horizon- tal diameter, and point C is at the bottom of the loop, as shown in the figure above. Assume that friction between the track and blocks is negligible. (a) The dots below represent the two connected blocks at points A, B, and C. Draw free-body dia- grams showing and labeling the forces (not com ponents) exerted on the blocks at each position. Draw the relative lengths of all vectors to reflect the relative magnitude of the forces.

They have a round turntable with a surface made from one of the materials, for which they can vary the speed of rotation. They also have a small block of mass m made from the sec- ond material. A rough sketch of the apparatus is shown in the figure below. Additionally they have equipment normally found in a physics classroom.

- In general it is best to conceptualize vectors as arrows in space, and then to make calculations with them using their components. (You must first specify a coordinate system in order to find the components of each arrow.) This problem gives you some practice with the components.
