(a) The diagram above illustrates a projectile motion. Identify each of the physical quantities labeled P, β, H and R.

(b) Write an equation to show the relationship between P, g and Rmax’ where g is the acceleration due to gravity and Rmax is maximum R.

The expected answer is

(a) Identification of labelled physical quantities

P  - initial velocity/ velocity of projection
b -   angle of projection
H -   maximum height reached
R -    range/horizontal distance (covered)

(b) Equation showing relationship between P, g and Rmax

Rmax = \(\frac{p^2}{g}\)
