Answer:
whirl a rock at the end of a string and it follows a circular path. if the string breaks, the tendency of the rock is to stop
The second statement is the correct choice. Don't make me type it out.
Speed can be shown on a graph of position versus time, and acceleration can be shown on a graph of speed versus time.
Answer:
The equation which define the work done by spring is w = 45 x³ - 8 x²
Explanation:
Given as :
The force is the function of distance x
I.e F(x) = a x² - b x
where
a = 45 N/m²
b = 8 N/m
Now, Wok done = Force ×displacement
I.e W = F . ds
So , W = (a x² - b x) × x
or, W = (45 x² - 8 x) × x
Or, w = 45 x³ - 8 x²
So, the equation which define the work done by spring is w = 45 x³ - 8 x²
Hence The equation which define the work done by spring is w = 45 x³ - 8 x² Answer
