A body of mass 
is launched at speed 
at an angle 
with respect to horizontal ground. The resistance of the air to the movement of the body is neglected.
Where is the body after the first second?
What is the potential energy of the body after the first second from the start of the throw?
What is the kinetic energy of the body after the first second from the start of the throw?
What is the kinetic and potential energy of the body at the highest point of the throw?
In the same coordinate system, draw the graphs of the potential, kinetic and total energy of the body against the time during the rising of the body.
