that mentioned this, but I only caught the end of it , and have never heard it mentioned again. If any one else recalls this, or can shed some light on it (pardon the pun) I'd appreciate it.

that i have no idea how to get..

1. find the equation of the tangent line to y=f(x), x=a.
f(x) = x^3 + x, a=1

2. use the position function f(t) to find the velocity at time t=a.
f(x) = -16t^2 + 5, a=2

a boat is being pulled toward a dock by means of a rope attached to the front tip of the bow. initially there are 30 ft. of rope out and the rope is taught and being reeled in by a circular device the top of which is 10ft. higher than the point where the rope is attached to the boat. this circular device has a radius of 1ft. and turns at the rate of one revolution every pi seconds. how fast is the boat moving along the water when there are 15ft. of rope out?

1. A worker pulls a sled with a force of 80 N directed at an angle of 60 degrees above the horizontal over a level distance of 6 m. If a frictional force of 24 N acts on the sled in a direction opposite to that of the worker, what net work is done on the sled?

a. 240 J, b. 216 J, c. 144 J, d. 96 J


2. A model rocket sits on the launch pad until its fuel is ignited, blasting the rocket upward. During the short time of blast-off, as the ignited fuel goes down, the rocket goes up because:

a. momentum is conserved in this process
b. the fuel pushes on the ground
c. air friction pushes on the escaping fuel
d. the downward force of gravity is less than the downward momentum of the fuel

please explain why you believe the answers are what they are just in case yours are different than mine. thanks a lot guys!
