Question

A projectile is shot from the ground at a velocity of `32 m/s` and at an angle of `(3pi)/4`. How long will it take for the projectile to land?

Answer 1

`t= ( 16 sqrt2)/5 sec`

Explanation:

Here,`u= 32m/s`, `theta= (3pi)/4`

`t = (2usintheta)/g`

`t= (2xx 32xx 1/sqrt2)/10`

`t= ( 32xx sqrt2/2)/5`

`t= ( 16 sqrt2)/5 sec`
