The automobile travels from a parking decl down along a cylindrical spiral ramp at a constant speed o v = 1.5 m/s. If the ramp descends a distance of 12 m fo every full revolution, 2 rad, determine the magnitud of the car's acceleration as it moves along the ramp r = 10 m. Hint: For part of the solution, note that th tangent to the ramp at any point is at an angle o = tan (12/[2 (10)]) = 10.81 from the horizontal Use this to determine the velocity components v, and v which in turn are used to determine 0 and . - 10 m 12 m
