Answer:
can be called kinetic or potential energy
Explanation:
Answer:
Explanation:
A)
v² = u² + 2as
a = (v² - u²) / 2s
a = (0² - 370²) / (2(0.130))
a = -526,538 m/s²
B)
t = v/a
t = 370 / 526538
t = 0.0007027... s or 0.7 ms
C)
F = ma
F = 0.00175(526,538) = 921.442307... = 921 N
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.
+1
An electron has a negative charge so losing a charge of -1 from an uncharged, or neutral, atom will leave an ion with a positive charge.
