1). Indicate whether the object will remain in circular motion or not for each case below. Show a calculation as proof. If it doesn’t stay in circular motion, state what happens to it.
a). A car traveling at a speed of 24 m/s around an unbanked curve with a radius of curvature of 108 m and a coefficient of static friction of 0.36 .
b). A person riding in a roller coaster car as it goes over the top of a curve with a radius of curvature of 33 m at a speed of 16 m/s.
