To anticipate a dip and a bump in the road the driver of a car applies her break to produce ga uniform deceleration . Her speed is 100km/hr at the bottom A of the dip and 50km/hr at the top C of the hump which is 120m along the road from A . If the passengers experiences a total acceleration of 3meter per second square at A . And if the radius of curvature at hump C is 150m . Calculate the radius of curvature of A . Calculate the acceleration at the point of inflexion B. find the acceleration at point C
1 answer
Acceleration at c is 2.3 meter per seconds
