Answer:
Explanation:
wavelength, λ = 3.4 m
wavelength, λ' = 3.3 m
Speed, v = 340 m/s
f = v / λ = 340 / 3.4 = 100 Hz
f' = v / λ' = 340 / 3.3 = 103.03 Hz
Frequency of beat, n = f' - f = 103.03 - 100 = 3.03 Hz
Assuming that the collision is inelastic that is they are stuck together after the collision, momentum is conserved. We can determine the final velocity of the final mass as follows:
m1v1 + m2v2 = m3v3
100(4) + (200)(-3) = (300)v3
v3 = -0.6667 m/s
Therefore, the final mass moves at 0.6667 m/s to the left.

1850 to 1900 because the slope would be 105. It says what is the greatest fall, so the upward slope of 120 wouldn't count.

Answer:
Acceleration, a=6.66\ m/s^2
Explanation:
Given that,
Force acting on the object, F = 500 N
Mass of the object, m = 75 kg
We need to find the acceleration of the object. The force acting on the object is given by :
a=\dfrac{F}{m}
a=\dfrac{500\ N}{75\ kg}
a=6.66\ m/s^2
So, the acceleration of the object is 6.66\ m/s^2. Hence, this is the required solution.
