A forklift is used to offload freight from a delivery truck. Together the forklift and its contents weigh 800 lb , and the weight is evenly distributed among four wheels .The ramp is inclined 14 ° from the horizontal. a. Write the force vector F in terms of i and j representing the weight against a single tire. b. Find the component vector of F parallel to the ramp. Round values to 1 decimal place. c. Find the magnitude of the force needed to keep the forklift from rolling down the ramp. Round to the nearest pound.

a. Write the force vector F in terms of i and j representing the weight against a single tire.
b. Find the component vector of F parallel to the ramp. Round values to 1 decimal place.
c. Find the magnitude of the force needed to keep the forklift from rolling down the ramp. Round to the nearest pound.
Quantities that have magnitude and direction but not position. Some examples of vectors are velocity, displacement, acceleration, and force. They are sometimes called Euclidean or spatial vectors.

In the integral dxf1dy (7)², make the change of variables x = ½(r− s), y = ½(r + s), and
evaluate the integral. Hint: Find the limits on r and s by sketching the area of integration in the (x, y) plane along
with the r and s axes, and then show that the same area can be covered by s from 0 to r and r from 0 to 1.
