Question

Spitting cobras can defend themselves by squeezing muscles around their venom glands to squirt venom at an attacker. Suppose a spitting cobra rears up to a height of 0.480 m above the ground and launches venom at 2.80 m/s, directed 55.0° above the horizon. Neglecting air resistance, find the horizontal distance (in m) traveled by the venom before it hits the ground.

 m

Answer 1

V_ox = 2.8 cos 55

V_oy = 2.8 sin 55

in y-direction

d = V_oy t + 1/2 a t^2

-0.48 = 2.8 sin 55 t + 1/2 (-9.8) t^2

solve the quadratic equation for t

in x-direction

d = V_ox t =
