I will help up you using these statements which I took for the same problem:
a) at the lowest position of the bob, the KE is equal to zero.
FALSE BECAUSE AT THE LOWEST POSITION THE PE IS THE LOWEST AND THE KE IS THE HIGHEST.
b) at the highest position of the bob, the PE is equal to zero.
FALSE BECAUSE AT THE HIGHEST POSITION THE PE IS THE HIGHEST
c) at the highest position of the bob, the KE is equal to zero.
TRUE: AT THE HIGHEST POSITION THE PENDULUM COMES TO ZERO SPEED AND SO THE KE IS ZERO.
d) at all the positions except the highest positions the PE is zero.
FALSE: THE PE ENERGY CHANGES WITH THE ALTITUDE AND IS ZERO ONLY AT THE BASE LEVEL.
38.71428571428571 or 38.7
For question (ii) I'm not sure if the answer is correct or not because I don't understand the question asked ...
I hope I can help ....
Hello!
Judging by the question you have provided I have come up with an equation to find the answer!
The equation is as follows: $0.25(Amount of quarters)(40) + $0.10 (Amount of dimes)(50) + $0.05 (Amount of nickels)(40) = Total Money!
First you want to input the amount of each coin(s) that you have.
Your new equation should be
$0.25 (4)(40) + $0.10 (3)(50) + $0.05 (6)(40).
If you solve the equation you should get $67.00 as your total!
Hope this helped!
