Mom is 30 years old when Serena is 10 because 10 x 3 = 30.
They are 20 years apart. [This is key]
Half (.5) of mom's age will be = to Serena's age.
Therefore, when mom is 40 years old, Serena is 20 years old.
We can see that half of 40 = 20.
Hope this makes sense!
g- acceleration due to gravity=9.8ms^-2
acceleration of performer= 1.5g = 1.5 x 9.8ms^-2 = 14.7ms^-2
