It is interesting to speculate on the properties of a universe with different values for the fundamental constants.
a. in a universe in which planck’s constant had the value h = 1 j s, what would be the de broglie wavelength of a 145 g baseball moving at a speed of 20 m/s?
b. suppose the velocity of the ball from part (a) is known to lie between 19 and 21 m/s. what is the smallest distance within which it can be know to lie?
c. suppose that in this universe the mass of the electron is 1 g and the charge on the electron is 1 c. calculate the bohr radius of the hydrogen atom in this universe

An engineer designs a roller coaster so that a car travels horizontally for 162 ft, then climbs 127 ft at an angle of 31.0° above the horizontal. it then moves 127 ft at an angle of 46.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)
