A bicyclist is stopped at the entrance to a valley, as sketched below: alo D Ar (choose one) Where would the bicyclist have the highest potential energy? (choose one) Where would the bicyclist have the lowest potential energy? (choose one) Where would the bicyclist have the highest kinetic energy? (choose one) Where would the bicyclist have the highest speed? Would the bicyclist's kinetic energy be higher at D or A? (choose one) Would the bicyclist's potential energy be higher at...

Using conservation of energy to predict the qualitative exchange A bicyclist is stopped at the entrance to a valley, as sketched below: Where would the bicyclist have the highest potential energy? Where would the bicyclist have the lowest potential energy? Where would the bicyclist have the highest kinetic energy? Where would the bicyclist have the highest speed? Would the bicyclist's kinetic energy be higher at B or A? Would the bicyclist's potential energy be higher at B or A? Would...

There was a car accident. Someone stopped and the person
behind them rear ended them. The car that stopped slid away about
30 feet and the car that did the rear ending stopped right about
where the collision happened. Was this a perfectly inelastic
collision? Why or why not?
A perfectly elastic collision is one in which kinetic
energy is conserved. How exactly is kinetic energy not conserved
though? Sometime KE can be used up compressing/bending things and
making heat,...

Conservation of energy In the examples you have examined in this lab, as the coaster travels down the track its gravitational potential energy decreases, and its kinetic energy increases. At any point along the path of the coaster, the potential energy plus the kinetic energy add up to the same value. In the absence of friction and air resistance, we find that the total energy (kinetic plus potential) stays the same. For this reason, physicists call the total energy a...

Consider the Kronig-Penney model discussed in the lectures, where the periodic potential corresponds to an array of delta functions: However, unlike the usual model, we will take α < 0, so that we have potential wells rather than barriers. In the following, we aim to solve the time-independent Schrödinger equation 2m r (a) First consider the case where the energy E 0. Write down the general solution for ψ(z) within the interval 0 < r < a, and use the...

PHOTOELECTRIC EFFECT LAB Enter your answers to Canvas. Objectives: The main objective of this lab is to observe the photoelectric effect experiment qualitatively. From the observations, you will summarize the important relationship between the properties of the photoelectrons (average speed, kinetic energy) to the properties of the incident light (wavelength, frequency). You will...

Then set up photogates in location 2 and 3. Measure the diameter (in m) of the metal balls (you will need it for speed calculations). Then, measure the weight (mass) of the ball (in kg). To have a better measurement of the time,...
