On may 16, 2019 the transiting exoplanet survey satellite (tess) discovered two exoplanets orbiting a nearby sun-like star, hd 15337, with mass ma = 0.90m⊙. we will focus on the information that led to the discovery of the further of the two planets. the time between transits is p = 17.2 days. during a transit, the time from first to second contact is t2 − t1 = 6.4 minutes and the time from first to third contact ist3 − t1 = 111 minutes. doing follow-up radial velocity measurements of the star, you find that the peak radial velocity is vr = 3.798 km/s.
a. what is the semi-major axis of the planet’s orbit in au? b. what is the radius of the planet in earth radii?
c. what is the mass of the planet in earth masses?

Two horses begin at rest. after a few seconds, horse a is traveling with a velocity of 10 m/s west, while horse b is traveling with a velocity of 13 m/s west. which horse had a greater acceleration? a. horse a because its change in velocity was greater than horse b's in the same time. b. horse b because its change in velocity was greater than horse a's in the same time. c. horse b because its change in velocity was the same as horse a's, but it took less time. d. both horses had the same acceleration.
