weight = 139 force = 428 (both rounded of course)

super huge numbers.

The sum of forces in the x-direc are the component of weight in the x and friction: F_x = W*sin(12) - F_friction The frictional force is 430. F_x is 0 since the car is not moving. Solve for W. W = 2068 lbs The sum of forces in the y-direc are the component of the weight in the y and the normal force: The sum of the forces in the y is 0 because the car is not sinking or floating F_y = F_Normal - W*cos(12) F_Normal = 2068 *cos(12) = 2023 lbs. ---this is the force the car exerts on the driveway.

ooki they give an example in the book. a) the magnitutde of the part of the force w that causes the car to roll down the driveway is |u|=component of w along u

F_x = W*sin(18) - F_friction The frictional force is 450. F_x is 0 since the car is not moving. Solve for W. W = 1456 lbs The sum of forces in the y-direc are the component of the weight in the y and the normal force: The sum of the forces in the y is 0 because the car is not sinking or floating F_y = F_Normal - W*cos(12) F_Normal = 1456*cos(18) = 1385 lbs. ---this is the force the car exerts on the driveway.

the force is 1385 and the weight is 1456?

yay that's right :) thanks so much!!
