A projectile is fired from the ground (you can assume the initial height is the same as the ground) in a field so there are no obstacles in its way. It is fired at an angle of 24° with respect to the horizontal and with an initial speed of 25 m/s. Air resistance is negligible in this situation. Call up the positive y-direction, and toward the wall the positive x-direction. What is the earliest time when the height of the...

A projectile is fired from the ground (you can assume the initial height is the same as the ground) in a field so there are no obstacles in its way. It is fired at an angle 11° with respect to the horizontal and with an initial speed of 46 m/s. Air resistance is negligible in this situation. Call up the positive y direction, and toward the wall the positive x direction. What is the earliest time when the height of...

A 23.0 kg cannon ball is fired from a cannon with a muzzle speed of 1100 m/s at an angle of 32.0° with the horizontal. A second ball is fired at an angle of 90.0°. a.) Use the conservation of energy principle to find the maximum height reached by each ball b.) What is the total mechanical energy at the maximum height for each ball? Let y = 0 at the cannon

2. A rocket of mass m is fired vertically from the Earth, with an initial speed U. It rises to a height R/2 before falling back to Earth, where R is the radius of the Earth. Calculate U in terms of G, M (the Earth's mass) and R. The rocket is fired with the same initial speed, but this time at an angle 45° to the horizontal. Calculate its angular momentum J and total energy E, and use these to...
