On a level ground a shell is fired with an initial velocity of 80.0 m/s at 60.0 degrees above horizontal and feels no appreciable air resistance. (a) find horizontal and vertical components of shell's initial velocity. (b) how long does the shell take to reach its highest point? (c) find its maximum height above ground. (d) how far from its firing point does the shell land? (e) will the shell clear a 160-m tall mountain located at a horizontal distance of 235.0 m from the firing point

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.
