The drawing shows a version of the loop-the-loop trick for a small car. the radius of the loop r = 0.50 m. what is minimum initial speed ( v ) that the car needs to have in order to remain in contact with the circular track at all times?

Isuck at math i am no sorry

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.

Not what goes around on earth but the universe too.
