Answer:
U = - ∫ F dx
U = - 3F₀
Explanation:
Force and potential energy are related
F =
dU = - F dx
∫ dU = - ∫ F dx
U- U₀ = - ∫ F dx
to solve the problem we must know the form of the force, if we assume that F = F₀ and U₀ = 0 for x = 0
U = - F₀ 3
You can approach this problem in an analytical way. The formula for kinetic energy is 1/2*mv². Throughout the projectile motion, mass is constant. Therefore, it wholly depends on the velocity.<em> So, the maximum kinetic energy is when the object travels the fastest. This is right when it leaves the launcher, and the moment just before it hits the ground.</em>
Answer:15th
Explanation:
I believe it will fall on the 15th stair because 10 times 15 is 150 divided by 10 m/s equals 15
Set up a unit conversion problem, arrange units to convert minutes to seconds, then cancel all time units.
8.3 minutes x (60 seconds/1 minute) x ( 3.00x10^8 meters/1 second) = 149,400,000,000 meters
Since the time is the term with the fewest number of significant figures (2), your answer should only be expressed with two sig figs as well.
1.5x10^11 m
Answer:
F = 15.47 N
Explanation:
Given that,
Q = 52 µC
q = 10 µC
d = 55 cm = 0.55 m
We need to find the magnitude of the electrostatic force on q. The formula for the electrostatic force is given by :

So, the magnitude of the electrostatic force is 15.47 N.
