 Some of students made mistakes when they differentiated the given Velocity profile.

 5 students did not differentiate the given velocity profile, and some of tried integration of the velocity profile

 Some of students used wrong surface area to get the Drag Force

 One student missed ‘𝛑’ to get the surface area,

 The Drag Force should be calculated by multiplying the surface area and the Pressure, but one student divided the pressure by the area to get Force.
