Question

If a projectile is shot at an angle of `pi/4` and at a velocity of `24 m/s`, when will it reach its maximum height??

Answer 1

`t=1.73" "s`

Explanation:

`"you can calculate using the formula t="(v_i*sin alpha)/g`

`alpha=pi/4" ; "sin(pi/4)=0.707" ; "v_i=24" "m/s`

`t=(24*0.707)/(9.81)`

`t=1.73" "s`
