Question

If a projectile is shot at a velocity of `16 m/s` and an angle of `pi/4`, how far will the projectile travel before landing?

Answer 1

`x_m=26.1" "m`

Explanation:

`x_m=(v_i^2*sin2alpha)/g`

`v_i=16" "m/s`

`alpha=pi/4`

`2*alpha=2*pi/4=pi/2`

`sin (pi/2)=1`

`x_m=(16^2*1)/(9.81)`

`x_m=256/(9.81)`

`x_m=26.1" "m`
