Answer:
7.894 Hours.
Explanation:
Based on information number hours that this battery will last with give load has mathematical relation of.
with load 60A t = 1h, 30A t = 2h so on and forth.
two head lights draw total current of 2x3.8A = 7.6A.
putting this in above relation gives.
.
That is how long will it be before battery is dead.
With an acceleration of 4.0 m/s², the bottle attains a speed of
(4.0 m/s²) * (9.0 s) = 36 m/s
so that the slide has length ∆<em>x</em> such that
(36 m/s)² - 0² = 2 * (4.0 m/s²) * ∆<em>x</em>
==> ∆<em>x</em> = 162 m ≈ 160 m
Alternatively, we know the bottle covers a distance ∆<em>x</em> with acceleration <em>a</em> at time <em>t</em> according to
∆<em>x</em> = 1/2 <em>a</em> <em>t</em>²
so that
∆<em>x</em> = 1/2 * (4.0 m/s²) * (9.0 s)² = 162 m ≈ 160 m
I'm pretty sure it's frying an egg because you can't un-fry the egg

G is the gravity which is usually a fixed number (10)
From definition 1 kWh = 3600000 J
The formula for KE = 1/2 * m * v^2
3600000 = 1/2 * 1000 * v^2
3600000 = 500v^2
v^2 = 7200
v = 84.85 m/s
