If an exit ramp on an expressway is designed with radius of curvature of 100 ft and maximum speed of 25 mph, determine the minimum bank angle. Consider the coefficient of static friction as 0.3 for this case.A 200-kg rocket sled is at rest when it is given a timed burn for 6 seconds, producing thrust of F(t) = 500(t' + 21) N. If the coefficient of static friction between the sled and the rails is 0.5, and the coefficient of kinetic friction is 0.4, determine a) the time before the sled starts to move, b) position and velocity of the sled at the end of the burn, c) total distance the sled will travel before coming to rest.
