For this problem, we use the derived equations for rectilinear motion at constant acceleration. The equations used for this problem are:
a = (v - v₀)/t
2ax = v² - v₀²
where
a is the acceleration
x is the distance
v is the final velocity
v₀ is the initial velocity
t is the time
The solution is as follows;
a = (60mph - 30 mph)/(3 s * 1 h/3600 s)
a = 36,000 mph²
2(36,000 mph²)(x) = 60² - 30²
Solving for x,
x = 0.0375 miles
Here i state the conservation of energy rule and use that to justify my answer. I showed how to manipulate percentages to get the final answer of 11000J (2sf). Hope I'm right xx
answer
v = 4.2
set up an equation
we can use the formula for kinetic energy since we know mass and kinetic energy
K = 
v = 
values
K = 0.013 J
m = 1.5g = 0.0015 kg
plug in values
v = 
v = 4.2
Uranus was originally discovered by Sir William Herschel in 1781. Neptune is the 8th planet from the sun making it the most distant in the solar system. Neptune is the smallest of the Ice Giants. The atmosphere of Neptune is made of Hydrogen, helium, And some methane. Uranus make one trip around the sun every 84 earth years. Uranus has the coldest temperatures of any planet. I hope This helps!!!
