You may attempt a solution to this problem and then post it, and I will mark it for you and help you if you battle t solve it, just let me know.
Explanation:
During a BMX freestyle competition in J-bay, a rider performs
a perfect wall ride. At what minimum velocity must he travel if he
wants to remain in contact with the wall for at least 3 m, if the
coefficient of static friction between his tyres and the wall is 0,50.
(Hint : The normal force provides the required centripetal force to
maintain motion in a 3 m radius circular section).
