Projectile motion

A projectile of mass m is launched over level ground with an initial speed
v at an angle theta to the horizontal. Neglecting air resistance, What is the kinetic energy just after launch? What is the total energy at the top of the flight?

Solution Preview

The Kinetic energy just after launch will be Ek = (1/2)*m*v^2

Thet total energy is conserved in a projectile ...
