Please help!! I need this asap! thank you so much!! <3 Compared to a ball thrown at 10 meters per second, which statement describes the change in kinetic energy of a ball of the same mass thrown at 20 meters per second?

1) The kinetic energy of the ball thrown at 20 meters per second is half (½×) the kinetic energy of the ball thrown at 10 meters per second.

2) The kinetic energy of the ball thrown at 20 meters per second is two times (2×) the kinetic energy of the ball thrown at 10 meters per second.

3) The kinetic energy of the ball thrown at 20 meters per second is the same as (=) the kinetic energy of the ball thrown at 10 meters per second.

4) The kinetic energy of the ball thrown at 20 meters per second is four times (4×) the kinetic energy of the ball thrown at 10 meters per second.

Assume the existence of a bankaccount class. define a derived class, savingsaccount that contains two instance variables: the first a double, named interestrate, and the second an integer named interesttype. the value of the interesttype variable can be 1 for simple interest and 2 for compound interest. there is also a constructor that accepts two parameters: a double that is used to initialize the interestrate variable, and a string that you may assume will contain either "simple", or "compound", and which should be used to initialize the interesttype variable appropriately. there should also be a pair of functions getinterestrate and getinteresttype that return the values of the corresponding data members (as double and int respectively).
