Answer:
3, 43,968.88 m
Explanation:
Let mass of the missile be m
velocity = 3500 m/s
smaller part will have zero horizontal velocity and larger part will have velocity v in horizontal direction
Applying conservation of momentum
m x 3500 = .35m x 0 + .65m x v
v = 5384.61 m / s
Height of explosion
h = 20000 m
time to fall be t
for vertical fall u = 0 , g = 9.8
20000 = 1/2 x 9.8 t²
= 63.88 s
Horizontal range
time of fall x horizontal velocity
= 63.88 x 5384.61
= 3, 43,968.88 m
The best answer would be:
B. Epi pen
Here is more about it:
An epi pen injects epinephrine into the body to counteract the effects of an allergic reaction. Epinephrine helps narrow blood vessels and open up the airways. This can be used for food allergies, insect bites, and some other allergens. It is very effective and immediately works, but it is short-lived, so seeking medical attention after is still needed.
