A ramp is used to help a person in a wheel chair up some steps that are 75 cm high. The person and chair together weigh 800 N. The greatest force that the person can exert is 200 N. Find the minimum length of the inclined plane that is required.

Paul’s car is 18 feet long. he is making a model of his car that is 1/6 the actual size. what is the length of the model?

Sketch the vector field vector f( vector r ) = 8vector r in the xy-plane. select all that apply. the length of each vector is 8. the lengths of the vectors decrease as you move away from the origin. all the vectors point away from the origin. all the vectors point in the same direction. all the vectors point towards the origin. the lengths of the vectors increase as you move away from the origin.
