Question

A projectile is shot from the ground at a velocity of `32 m/s` and at an angle of `(pi)/2`. How long will it take for the projectile to land?

Answer 1

`"time elapsed is 6.52 seconds"`

Explanation:

`"t:time elapsed"`
`v_i:"initial velocity"`
`alpha:"angle"`
`g=9.81" "N/(kg)`

`t=(2*v_i*sin alpha)/g`

`t=(2*32*1)/(9.81)`

`t=64/(9.81)`

`t=6.52" "s`
