The mass of the Book is 2.27 kg.
It’s B I’m not sure it the right one
Answer:
the average net force on the truck is 3744 N.
Explanation:
Given;
mass of the truck, m = 1200 kg
initial velocity of the truck, u = 25 m/s
final velocity of the truck, v = 53 m/s
distance traveled by the truck, d = 350 m
The acceleration of the truck is calculated as;
v² = u² + 2ad
53² = 25² + (2 x 350)a
700a = 53² - 25²
700a = 2184
a = 2184 / 700
a = 3.12 m/s²
The average net force on the truck is calculated as;
F = ma
F = 1200 x 3.12
F = 3744 N
Therefore, the average net force on the truck is 3744 N.
The frequency is ![6.67\cdot 10^4 Hz](https://tex.z-dn.net/?f=6.67%5Ccdot%2010%5E4%20Hz)
Explanation:
For a periodic motion:
- The period (T) of the motion is the time it takes for the body to make one complete oscillation.
- The frequency (f) of the motion is the number of complete oscillations made in one second
Frequency and period are related by the equation:
![f=\frac{1}{T}](https://tex.z-dn.net/?f=f%3D%5Cfrac%7B1%7D%7BT%7D)
where
f is the frequency
T is the period
For the motion in this problem, we have:
is the period
Therefore, the frequency is:
![f=\frac{1}{15\cdot 10^{-6}}=6.67\cdot 10^4 Hz](https://tex.z-dn.net/?f=f%3D%5Cfrac%7B1%7D%7B15%5Ccdot%2010%5E%7B-6%7D%7D%3D6.67%5Ccdot%2010%5E4%20Hz)
