Question #0bcbf

Answer 1

Treating horizontal and vertical motions independently as these are orthogonal.
Time taken to cover `100m` with initial horizontal velocity of `500ms^-1`
`t="Distance"/"Velocity"=100/500=0.2s`

The bullet falls freely under gravity in vertical direction with initial velocity of `0`. Vertical defection in vertical in `0.2s` is found using the kinematic equation
`d=ut+1/2g t^2`
`=>d=0xx0.2+1/2 xx9.81xx (0.2)^2~~0.196m`
`=>d=~~0.196m`
