Circle the letter to the left of the selection to indicate your answer a = 3; b= 4; c = 6; a = b*(a^2 + c) + c^2/b; 9.00 69.00 627.52 5.647.80 all of the above solutions are correct none of the above solutions is correct You have been given a physics problem to solve with a Matlab program A car whole engine has died is moving up a hill on its own kinetic energy (1/2 mv^2 where m is man and v is velocity) At some point up the hill, the car will stop, and at that moment. It will have a only potential energy (mgh, where m Is mass, g Is the acceleration of gravity, and h is the height above the ground). When the car comes to a halt, the potential energy will not equal the initial kinetic energy due to the friction lost in the car; to calculate this friction, the potential energy must be subtracted from the initial kinetic energy. From the following, select the best example of how this would be Implemented in pseudo code. Circle the letter to the left of the selection to indicate your answer. %calculate friction lost %calculate potential energy %calculate energy difference %calculate kinetic energy % calculate friction lost %calculate energy difference %calculate kinetic energy %calculate potential energy %calculate friction lost %calculate kinetic energy %calculate energy difference %calculate potential energy %Calculate friction lost %calculate kinetic energy %calculate potential energy %calculate energy difference

Explanation / Answer

Hi

I have solved your problem given above. Please review and confirm if you are clear with solution approach.

Answer for question number 8-

c= a^2-c/a+b/a*c

c= ((3^2)-(9/3)+((6/3)*9)) [Puting the Brackets as per the precedence order]

c= (9-3+(2*9)) [3^2=9, 9/3=3 and 6/3=2]

c= (9-3+18)

c= (27-3)

c= 24 [Answer]

Answer D

Answer for Question 9-

a= b*(a^2+c)+c^2/b

a= 4*(3^2+6)+6^2/4 [ Put the values as given in question in place of variables]

a= (4*((3^2)+6)+(6^2)/4) [ Applying brackets as per the operator precendence]

a= (4*(9+6)+(36/4)) [6^2=36, 3^2=9]

a= (4*15+9)

a= 60+9

a= 69 [Answer]

Correct Answer is D.
