The net force simply the sum of two forces:
Negative and positive are assigned to those forces to show direction because it is a vector.
So, given that left is negative and right is positive;
<em>a)</em>
2.30N - .800N = 1.50 N
Given the equation F = ma, where m= 0.125 (mass) and F = 1.50 (force), we can solve for a (acceleration).
<em>b)</em>
1.50 N = (0.125 kg) a
a = 12.0 ms^-2
Answer:
a) Displacement of the object from t = 0 to t = 3 is 1.5 m
b) Distance of the object from t = 0 to t = 3 is 1.83 m
Explanation:
Velocity, v(t) = t² - 3t + 2
a) Displacement is given by integral of v(t) from 0 to 3.
b) t² - 3t + 2 = (t-1)(t-2)
Between 1 and 2, t² - 3t + 2 is negative
So we can write t² - 3t + 2 as -(t² - 3t + 2)
Distance traveled
To solve this problem it is necessary to apply the concepts related to the described wavelength through frequency and speed. Mathematically it can be expressed as:
Where,
Wavelength
f = Frequency
v = Velocity
Our values are given as,
Speed of sound
Keep in mind that we do not use the travel speed of the ambulance because we are in front of it. In case it approached or moved away we should use the concepts related to the Doppler effect:
Replacing we have,
Therefore the frequency that you hear if you are standing in from of the ambulance is 0.1214m

Answer:
Newton's second law
Newton's second law, which states that the force F acting on a body is equal to the mass m of the body multiplied by the acceleration a of its centre of mass, F = ma, is the basic equation of motion in classical mechanics.
