If you neglect air resistance, then you can solve for the horizontal distance using the formula:
dx=vixt
Where:
dx = horizontal distance
vix = initial horizontal velocity
t = time in flight
Now you can see that you have all the given you need.
vix= 2km/h
t = 0.25 hours
We use hours because you need the units to be the same. So just plug that in your equation and you will have your answer:
dx = vixt
=(2km/h)(0.25h)
=0.5km
This means that the answer to your question is B.
396 years, 198 years out, and 198 more years to return in 2395, assuming an immediate response. Radio travels at the speed of light. A light-year is the distance light (or radio) travels in a standard earth year.

Answer:
<em>If you have any questions, comment</em>
Explanation:
a. time of flight =(2usinθ)/(g/6)
= 12usinθ/g
= (12x25xsin(30))/g
<h3>
= 15.306 seconds
</h3>
b. Range = u2sin(2θ)/(g/6)
= 6u2sin(2θ)/g
= (6x252xsin(60)) /9.8
= 331.387 metres
c. Range on earth = Range on moon/6 = 55.23 metres
On moon it travels 331.387 - 55.23 = 276.155 metres more than on earth
