A marksman fires a practice round from A toward a target B. If the target diameter is 160 mm and the target center is at the same
altitude as the end of the rifle barrel, determine the range of "shallow" launch angles for which the round will strike the target.
Neglect aerodynamic drag and assume that the round is directed along the vertical centerline of the target. (Note: The word "shallow"
indicates a low-flying trajectory for the round.)

At the northern tropic which you may take to be at 19 degrees north, air rises directly upwards from the surface of the Earth due to thermal forces at a speed of 45 m/s. What is the magnitude of the Coriolis and Centrifugal acceleration felt by the rising air due to the rotation of the Earth?
At the northern tropic which you may take to be at 23 degrees north, air rises directly
upwards from the surface of the Earth due to thermal forces at a speed of 30 m/s. What
is the magnitude of the Coriolis and Centrifugal acceleration felt by the rising air due to the
rotation of the Earth? (You may take the radius of the earth to be 6.37 million meters).

- You are on a boat in the middle of the Pacific Ocean at the equator traveling in a hydrofoil going at a constant speed of 300 m/s. The water is perfectly still. What is your acceleration: a) If you’re heading due North? b) If you’re heading due East? c) If you’re heading straight up (something probably went wrong at this point). You may assume the following: The earth has a radius of 6371 km. The earth makes one full revolution every 24 hours. The gravitational constant at sea level is 9.81 m/s2. East and North are relative to the Earth’s axial north, not magnetic north.arrow_forwardA spaceship is traveling through deep space towards a space station and needs to make a course correction to go around a nebula.
