SUMMARY
The maximum height of a projectile launched at 40 m/s at an angle of 60 degrees can be determined using the conservation of energy principle. The initial kinetic energy (KE) is calculated as (1/2)*m*(40 m/s)^2, while at maximum height, the kinetic energy is only due to the horizontal component (vx). The vertical component (vy) can be derived from the initial velocity, allowing the equation m*g*h = KE_initial - KE_final to be used to solve for height h.
