Force = the mass of an object x its acceleration
F=ma where f is force, m is mass, and a is acceleration.
The net force is 40-24=16N and the box is 8kg.
You can rearranage f=ma to make a the subject by dividing by m, so f/m=a
16/8=2m/s^2
Answer:
3.21
Explanation:
The relation between frequency and wavelength is shown below as:
c is the speed of light having value
Given, Frequency = 93.5 MHz =
Thus, Wavelength is:
<u>Answer - A.</u>
5.2m/s
Explanation:
Given parameters:
Mass of baseball = 0.15kg
Momentum of baseball = 0.78kgm/s
Unknown:
Speed of baseball = ?
Solution:
The momentum of the baseball is a function of the product of the mass and velocity. It is a vector quantity:
Momentum = mass x velocity
Since the speed of the ball is unknown:
Velocity =
= ![\frac{0.78}{0.15}](https://tex.z-dn.net/?f=%5Cfrac%7B0.78%7D%7B0.15%7D)
= 5.2m/s
The speed of the baseball before it lands is 5.2m/s
