<span>We know that v = u + at
He stops when the speed is zero; therefore
0 = 15 - 3.35 t
t = 4.48
It takes 4.48 seconds after the driver turns on the brake for him to stop.
We know
s = ut + (1/2)at</span>²<span>
s = 15*4.48 - *(1/2)(3.25)(4.48)</span>²<span>
s = 33.4 meters
The distance he travels before applying the brakes is:
s = 0.21 * 15
s = 3.15 m
The total distance he travels is:
3.15 + </span>33.4 = 36.55 meters
He will be able to stop in time.
Use the formula for energy stored between the plates of a capacitor:
where Q is he charge (given) and U is the electric potential (aka voltage), given.
The stored energy is 2.2 10^{-10} Joules.
After doing some research on Wiki, Google, and Easyscienceforkids, I have come to a conclusion that:
Mass: 5.972 * 10^24 kg
Radius: 3958.8 mi
Distance from the sun: 92.96 million mi
A famous person that makes me happy would Siennamae; her platform is based on body positivity and encouraging people to be more confident about who they are. A mobile app that makes me happy would be uber eats, this is because it allows me to order food at any given time of the day and i love food. An opportunity that makes me smile would be the opportunity to help the homeless and the orphans in the future because of how messed the system is, thinking about helping people brings joy to my heart.
A solution is a value or a collection of values.. when substituted for the unknowns, the equation become an equality.
Example : x + 2 = 7
When we out the 5 in place of x we get: 5 + 2 = 2
