Answer:
b=-20
Step-by-step explanation:
We will have to solve this question based on how the question is given
So let's solve the given question
2=7+b/4
To start by finding the LCM for the right side and the LCM is 4
2=28+b/4
Let's cross multiply
2×4=28+b
8=28+b
Let's make b the subject of formula by substrating 28 from both sides
-20=b
Therefore the final answer is b=-20
Keep in mind this relationship
1. Relationship between Speed, Distance and time
→Distance = Speed × Time

2. Relationship between Displacement, Velocity and time
→Displacement = Velocity × Time

So, velocity is zero only when
Displacement= 0,so when motion is circular motion,
Total Displacement =0 because initial and final position are same.
But , Speed is not zero, because
Total Distance Traveled = 2 π × (Radius of circle).
So, Option (A)The Starting and end point are same .. . . . in which the velocity is zero but the speed is a nonzero quantity.
Answer:

Step-by-step explanation:
The general solution will be the sum of the complementary solution and the particular solution:

In order to find the complementary solution you need to solve:

Using the characteristic equation, we may have three cases:
Real roots:

Repeated roots:

Complex roots:

Hence:

Solving for
:

Since we got complex roots, the complementary solution will be given by:

Now using undetermined coefficients, the particular solution is of the form:

Note:
was multiplied by x to account for
and
in the complementary solution.
Find the second derivative of
in order to find the constants
and
:

Substitute the particular solution into the differential equation:

Simplifying:

Equate the coefficients of
and
on both sides of the equation:

So:

Substitute the value of the constants into the particular equation:

Therefore, the general solution is:
