The formula below decribes Newton's second law of motion

Force = Mass x acceleration

Using the variables below Write one line of code that will calculate the acceleration of a object.

// Mass in Kg

float mass = 50.3;

// Froce in N

int force = 720; 

//acceleration

float accel;

//One line of code to calculate the acceleration of a object

What will the value of the answer variable be after the code segment below has been run.

(round to 4 decimal places)

float answer;  

int number1 = 67, number6 = 51;

float number11 = 32.9701;  

answer = ( number1 - number6 ) + number11;
