2. (8 marks) Air A popular science demonstration is to levitate a ping pong ball with an air jet, because if you push the ball off to the side, the ball will always return to the centre. (a) 2 marks. Briefly explain this phenomenon using the Bernoulli equation. (b) 6 marks. Estimate the velocity of the air if the ball has a mass of 2.5 g and a diameter of 3.8 cm.

CODE GIVEN
% Create a program to plot the motion of the ping pong ball with
drag.
% The program will take inputs for velocity in m/s and angle of
launch.
% note that with a high speed camera I estmated a launch speed
for a ping
% pong ball could be 30 m/s.
vel=30; %m/s
angle=60;
% convert the degrees into radians so MATLAB likes it
angle=angle*pi/180;
% set initial values (time, distance, mass, gravity, drag)
x(1)=0; % meters...
