    We won't simply give you the answer to this homework problem. But t get you started - I suggest you first draw a free body diagram with the forces that are acting on the skydiver's body. Then consider the fact that his velocity is constant - what does that mean regarding the net force acting on his body? Post back with your attempt at this and we'll help you along of you are still stuck.

The velocity as a function of time for an asteroid in the asteroid belt is given by v(t)= v0e^(t/t0) I + v0t/2t0 j with vo and to constants. Use ti = 0 as the initial time, and tf = 1.5 to as the final time. The values for the constants that you will use are: vo = 4.5 m/s
