sally is riding her bicycle on a path when she comes around a corner and sees that a fallen tree is blocking the street 42 meters ahead. if the coefficient of friction between her bike's tires and the gravel path is .36 and she is traveling at 50000 meters per hour how much stopping distance will she require? sally and her bike have a mass together of 95 kilograms and also

a box weighing 215 newtons is placed on an inclined plane that makes a 45.0 degree angle with the horizontal...compute the component of the gravitational force acting down the inclined plane....if the coefficient of static friction has a maximum value of .35, will the box slide down the plane?

i can draw the pictures for both i just do not know what to do next...please any help you have would be great
