Take a look at a bicycle with gears. using what you have just learned, answer the following questions:

which gear combination would you like to use when you want to pedal with as few strokes as possible and have your wheels turn as many times as possible?
now you are going up a hill and want to maximize the force you deliver to the wheel. you aren’t concerned with how many strokes you are making, but you want to get as much force to the wheel as possible. which gear combination would you use now, and why?

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west

c) power lifting, will be your answer.
