Idaho jo is doing physics experiments throughout the solar system. she travels to each planet and shoots a potato straight up in the air with her potato gun. she uses the same potato on each planet and the initial velocity is the same every time. she repeats the experiment on all 8 planets in the solar system.
planet free-fall acceleration
mercury 3.7 m/s2
venus 8.9 m/s2
earth 9.8 m/s2
mars 3.6 m/s2
jupiter 24.9 m/s2
saturn 10.6 m/s2
neptune 11.7 m/s2
uranus 8.9 m/s2
on which planet(s) will the potato reach the highest altitude?
mercury / mars
venus / uranus
earth
jupiter

Emmy kicks a soccer ball up at an angle of 45° over a level field. she watches the ball's trajectory and notices that it lands, two seconds after being kicked, about 20 m away to the north. assume that air resistance is negligible, and plot the horizontal and vertical components of the ball's velocity as a function of time. consider only the time that the ball is in the air, after being kicked but before landing. take "north" and "up" as the positive ‑ and ‑directions, respectively, and use ≈10 m/s2 for the downward acceleration due to gravity.

Athin nonconducting rod with a uniform distribution of positive charge q is bent into a circle of radius r. the central perpendicular axis through the ring is a z-axis, with the origin at the center of the ring. a) what is the magnitude of the electric field due to the rod at z = 0? n/c (b) what is the magnitude of the electric field due to the rod at z = infinity? n/c (c) in terms of r, at what positive value of z is that magnitude maximum? r (d) if r = 4.00 cm and q = 9.00 µc, what is the maximum magnitude? n/c

Refrigerant-134a flows through a carnot heat pump cycle at 0.5 kg/s. it is known that the maximum absolute temperature in the cycle is 1.1 times the minimum absolute temperature, and the net power input to the cycle is 2.5 kw. if the refrigerant changes from a saturated vapor to a saturated liquid during the heat rejection process, determine the maximum magnitude of the enthalpy of vaporization for this process in kj/kg (with 3 significant figures).
