Question

If a projectile is shot at an angle of `pi/4` and at a velocity of `2 m/s`, when will it reach its maximum height??

Answer 1

height = 20 cm

Explanation:

since `ke` =`1/2mv^2`
`K.E=1/2m2^2`
`k.e=2m J`

but K.e =workdone=potential energy of the body at maximum height

therefore`2m=mgh`

2=10h

`h=1/5m`
or`h=20cm`
