The velocity of Ned as measured by Pam is the interpretation of v.
Answer: Option D
<u>Explanation:</u>
According to question, we know that this is an issue depending on the logical and translation of the factors. From the measured information taken what is gathered by the two people is communicated and we have given as:
The Ned reference framework : (x, t)
The Pam reference framework :
From the reference framework, we realize that ν is the speed of Pam (the other reference framework) as estimation by Ned.
At that point, is the speed of Ned (from the other arrangement of the reference) as estimation by Pam.
Answer:
Fa=774 N
Fb=346 N
Explanation:
We will solve this problem by equating forces on each axis.
- On x-axis let forces in positive x-direction be positive and forces in negative x-direction be negative
- On y-axis let forces in positive y-direction be positive and forces in negative y-direction be negative
While towing we know that car is mot moving in y-direction so net force in y-axis must be zero
⇒∑Fy=0
⇒
⇒
⇒
Given that resultant force on car is 950N in positive x-direction
⇒∑Fx=950
⇒

Therefore approximately, Fa=774 N and Fb=346 N
