Using the expression we derived above, work out the minimum speed at which you can travel around the banked curve, using these values:
g = 10 m/s2; r = 160 m; tangent of the angle = 1/4 (this corresponds to an angle of 14 degrees); coefficient of static friction = 0.20.
Hint: if the tangent of the angle is 1/4, then the sine of the angle divided by the cosine of the angle is 1/4, which means that the cosine of the angle is 4 times the sine of the angle.
Calculate the minimum speed, with the values above.
_______ m/s
Numeric Answer:
Question 6
What is this in miles per hour?
_______ miles/hr

Write a MATLAB Graphical User Interface (GUI) to simulate and plot the projectile motion – the motion of an object projected into the air at an angle. The object flies in the air until the projectile returns to the horizontal axis (x-axis), where y=0. This MATLAB program should allow the user to try to hit a 2-m diameter target on the x-axis (y=0) by varying conditions, including the lunch direction, the speed of the lunch, the projectile’s size, and the...
