You and your friend are playing running catch, where you run towards each other while throwing a ball back and forth. If you are running at 1.00 m/s, your friend is running at 2.00 m/s, and you can throw the ball at 10.0 m/s, how far will the ball have traveled if you
start 500 m apart? Assume the time it takes to catch and then throw the ball is negligible.
O 500.0 m
O 1670 m
O 5000 m
O 1500 m

Ogle–2013–blg–0723 is an exoplanet that is similar to earth in size and proximity to its star. this exoplanet has mass m=4.18×1024kg and radius r=5.66×106m. an astronaut whose weight on earth is w=735n lands on the planet. a. calculate m, the mass of the astronaut. b. calculate gp? , the acceleration due to gravity on the surface of ogle–2013–blg–0723. c. calculate wp? , the weight of the astronaut on the surface of ogle–2013–blg–0723. d. calculate v, the minimum velocity required to put an object into orbit above ogle–2013–blg–0723. e. calculate t, the time required to complete an orbit around ogle–2013–blg–0723.
