Question

a shell is fired vertically upwards with velocity v1 from a trolley moving horizontally with velocity v2 . a person on the ground observes the motion of shell as a parabola whose horizontal range is ?

Answer 1

A shell is fired vertically upwards with velocity v1 from a trolley moving horizontally with velocity v2 . a person on the ground observes the motion of shell as a parabola whose horizontal range is 2 V1 V2/g.

Explanation:

Formula of horizontal range is the following;

x = V2 *t

Hence,

ℎ = V1*t − 1/2* g* t^2 = 0

Therefore,

t = 2*V1/g
