(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.
Explanation
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 = \(\frac{p^2}{g}\)
