Answer:
1110 N
Explanation:
First, find the acceleration.
Given:
Δx = 300 m
v₀ = 85.5 km/h = 23.75 m/s
v = 0 m/s
Find: a
v² = v₀² + 2aΔx
(0 m/s)² = (23.75 m/s)² + 2a (300 m)
a = -0.94 m/s²
Find the force:
F = ma
F = (1180 kg) (-0.94 m/s²)
F = -1110 N
The magnitude of the force is 1110 N.
Answer:a means of solving a problem or dealing with a difficult situation.
Explanation:Some examples of solutions are salt water, rubbing alcohol, and sugar dissolved in water. When you look closely, upon mixing salt with water, you can't see the salt particles anymore, making this a homogeneous mixture. Let's make use of our salt water example to talk about the two main parts of a solution.
Answer:
Vtennis = 134 [cm^3]; Vgolf = 40.76 [cm^3]
Explanation:
To solve this problem we must have the values of the radius or diameters of each of these balls, therefore performing an internet search we can appreciate that the diameters of these balls are:
Dt = 6.35[cm]
Dg = 4.27[cm]
But we need the radius, and we know that the radius is equal to the half of the diameter.
Rt = 3.175 [cm]
Rg = 2.135 [cm]
Now replacing this values in the given equation:
![V = \frac{4}{3} *\pi *r^{3}\\ V_{tennis}= \frac{4}{3} *\pi *(3.175)^{3}\\ V_{tennis}= 134.06[cm^3]\\\\ V_{golf}= \frac{4}{3} *\pi *(2.135)^{3}\\V_{golf}= 40.76 [cm^3]](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%7B4%7D%7B3%7D%20%2A%5Cpi%20%2Ar%5E%7B3%7D%5C%5C%20V_%7Btennis%7D%3D%20%5Cfrac%7B4%7D%7B3%7D%20%2A%5Cpi%20%2A%283.175%29%5E%7B3%7D%5C%5C%20V_%7Btennis%7D%3D%20134.06%5Bcm%5E3%5D%5C%5C%5C%5C%20V_%7Bgolf%7D%3D%20%5Cfrac%7B4%7D%7B3%7D%20%2A%5Cpi%20%2A%282.135%29%5E%7B3%7D%5C%5CV_%7Bgolf%7D%3D%2040.76%20%5Bcm%5E3%5D)
