SUMMARY
The maximum height of a projectile launched at a speed of 45 m/s and an angle of 56° can be calculated using the conservation of energy principle. The relevant equations include potential energy (PE) and kinetic energy (KE), specifically mgh = 1/2 mv². The vertical component of the initial velocity must be considered, which can be derived using the formula h = 0.5(v_y²)/g, where v_y is the vertical component of the initial velocity. The angle significantly influences the calculation of maximum height.
