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 average speed can be calculated by dividing the total distance traveled by the total time taken.
<h3>What is the average speed?</h3>
The average speed of a vehicle can be calculated by finding the ratio of the total distance traveled and the total time taken on the journey.
Average speed = total distance covered/total time taken
Since there are markers that indicate every 100-meter journey. The total number of such marker posts encountered multiplied by 100 will give an estimate of the total distance traveled in meters.
A record of the time taken on the journey will give the total time taken.
Hence, average speed = total number of marker posts x 100/total time.
The unit will be in m/s.

Answer:
It is also the energy dissipated as heat when an electric current of one ampere passes through a resistance of one ohm for one second. It is named after the English physicist James Prescott Joule (1818–1889).
Explanation:
They would hit the ground at the same time. No matter the weight laws of physics.
