Aweb page designer creates an animation in which a dot on a computer screen has position
r⃗ =[4.0cm+(2.5cm/s2)t2]ı^+(5.0cm/s)tȷ ^
. (a) find the magnitude and direction of the dot’s average velocity between t = 0 and t = 2.0 s.(b) find the magnitude and direction of the instantaneous velocity at t = 0, t = 1.0 s, and t = 2.0 s. (c) sketch the dot’s trajectory from t = 0 to t = 2.0 s, and show the velocities calculated in part (b).

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).
