understandable terms created for the physichs terms can create mass destruction in the fires created with force

**Answer:**

**Explanation:**

Given

Frequency of an object in SHM is

Frequency in SHM is given by

where k=spring constant

m=mass of object

if spring is exchanged such that new spring constant is half of previous one then

i.e.

You haven't told us what the passing percentage is on the exam,

or what the passing percentage is for the semester, or any of that.

Find the amount of work that the spring does. This can be found using the equation 1/2kx^2. Then, you must set that equal to the amount of kinetic energy the car has. This is possible thanks to the work-energy theorem.

1/2kx^2 = 1/2mv^2

Solve to find velocity. Remember, the spring is displaced .15 m, not 15!

To find the acceleration, use F = ma. The force being applied to the car is kx, and you know the mass. You do the math.

For problem C I don't know, haven't done that yet in my class. Sorry!

The answer is C as in cat
