A projectileof massm is launched over level ground with an initial speedv at an angle theta to the horizontal. Neglecting air resistance, what is the kinetic energyjust after launch? What is the total energy at the top of the flight?
The Kinetic energy just after launch will be Ek = (1/2)*m*v^2
Thet total energy is conserved in a projectile …
The solution determines the kinetic energy just after launch. It also calculates the total energy at the top of the flight.
