(d) Are anyof the answers changed if the initial angle is changed?

Find the minimum initial speed of a projectile in order for it to reach a height of 2145 km above the surface of the earth
when the velocity of a body is doubled, its kinetic energy is also doubled. true or false?
Use the conservation of energy todetermine the minimum vertical speed that anobject must have at the surface of the earth sothat its speed at infinity would be zero. Thisspeed is known as the escape speed of theearth. For this problem, you should assume thatthe gravitational interaction with the earth isthe only interaction which the object feels.
The initial kinetic energy imparted to a 0.022 bullet is 1300 J. Find the range of this projectile when it is fired at an angle such that the range is equals the maximum height attained.
