Asked by eddie
A bomber in level flight, flying at 92m/s, releases a bomb at a height of 1950m.
(a) How long is it before the bomb strikes earth? (19.9s)
(b) How far does it travel horizontally? (1832m)
(c) What are the horizontal and vertical components of its velocity when it strikes? (195m/s)
(d) What is its velocity of impact? (216m/s)
i understand a and b , i just need help with c and d.
can u show all ur steps please, thank you!

horizontal is constant at 92 m/s
vertical is 9.8*19.9
so, (d) is just the resultant speed s, where s^2 = h^2 + v^2
