You would like to shoot an orange out of a tree with your bow and arrow. The orange is hanging 5.00 m above the ground. You fire the arrow at 36.0 m/s oriented 30.0° above the horizontal from a height of 1.40 m while standing 57.0 m away on your first try. You may neglect air resistance. What is the height of the arrow once it has travelled the 57.0 m horizontally?
A space vehicle is orbiting Earth in the circular orbit with a radius of 10,300,000 m. What is the minimum increase in speed that is essential for the vehicle to escape Earth's gravitational field? The mass of Earth is 5.97 x 10^24 kg and G = 6.67 X ..
