The equation of motion of a projectile is y = 12 x - 3 4 x 2 , where x and y are in metre. What is the range (in m ) of the projectile?

y = 12 x - 3 4 x 2 Range is the point where y = 0 thus 0 = 12 x - 3 4 x 2 ⇒ x = 0 or x = 16 m

The equation of motion of a projectile is $y = 12 x - \frac{3}{4} x^{2}$ , where $x$ and $y$ are in metre. What is the range (in $m$ ) of the projectile?

Answer:

16.00

Solution:

$y = 12 x - \frac{3}{4} x^{2}$

Range is the point where $y = 0$

thus $0 = 12 x - \frac{3}{4} x^{2}$

$\Rightarrow$ $x = 0$

or $x = 16 m$
