Answer:
Step-by-step explanation:
Part A
xf = xo + vo* t + 1/2 a*t^2                    Subtract xo
xf - xo = 0*t + 1/2 a*t^2                        multiply by 2
2(xf - xo) = at^2                                    divide by t^2
2(xf - xo ) / t^2 = a
Part B
Givens
xo =0
vo = 0
a = 10  m/s^2
xf = 120 m
Solution
xf = xo + vo* t + 1/2 a*t^2              Substitute the givens
120 = 0 + 0 + 1/2 * 10 * t^2            Multiply by 2
120*2 = 10* t^2                   
240 = 10*t^2                                  Divide by 10
240/10  = t^2 
24 = t^2                                          take the square root of both sides.
√24 = √t^2
t = √24
t = √(2 * 2 * 2 * 3)
t = 2√6
 
        
             
        
        
        
Answer:
He can make a cake that serves 24 people.
Step-by-step explanation:
Gareth has 13 eggs, but only 2 are needed for 4 servings. 13 divided by 2 equals 6.5. We can't serve half of a person, so there will be a large cake equivalent to the size of 6 small cakes. Since 1 small cake serves 4 people, and Gareth's large cake is 6 times the size of a small cake, Gareth's cake can serve a total of 24 people. Now that is one big cake!
