If a particle is projected vertically upward in a constant gravitational field with an initial speed v0. If there is a retarding force proportional to the square of the instantaneous speed, the speed of the particle when it returns to the intial position is v0vt/√(v02+vt2) where vt is the terminal speed.
Assumptions: Kinetic Energy=KE, Potential Energy=PE m=mass of the skateboarder=55 kg, Velocity v=1.80m/s So ,Initial Energy(KE) of the skateboarder=mv 2 /2 = 0.5* 55 * (1.8)^
