Force= distance/time
Maybe that formula will help
Answer:
Chemical potential energy is the energy stored in the chemical bonds of a substance. The various chemicals that make up gasoline contain a large amount of chemical potential energy that is released when the gasoline is burned in a controlled way in the engine of the car. The release of that energy does two things
Explanation:
The formula for potential energy depends on the force acting on the two objects. For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters.
Answer:
The answer will be the first one.
Explanation:
Divide
Answer:
a) k = 120 N / m
n b) f = 0.84 Hz
, c) v = 1,056 m / s
, d) x=0
Explanation:
a) To find the spring constant let's use Hooke's law
F = - k x
k = -F / x
k = - 24.0 / (0.2)
k = 120 N / m
b) the angular velocity in harmonic motion is
w = √ k / m
w = √ 120 / 4.30
w = 5.28 rad / s
The angular velocity is related to the frequency
w = 2π f
f = w / 2π
f = 5.28 / 2π
f = 0.84 Hz
c) System speed is
v = dx / dt = -A w sin (wt +φ)
The speed is maximum when sin (wt + φ) = ±1
v = A w
v = 0.200 5.28
v = 1,056 m / s
d) in which position the velocity is maximum, as the velocity is a function of the sine and the position of the cosine when the sine is maximum the cosine is zero, so
x = A cos 0 = 0
x=0
