. The jet strikes a vane that moves to the right at constant velocity Vc on a frictionless cart. Compute (a) the force Fx required to restrain the cart and (b) the power P delivered to the cart. Also find the cart velocity for which (c) the force Fx is a maximum and (d) the power P is a maximum.

How well does the extrapolated value (the slope of the trend line) agree with the accepted value of free-fall acceleration (g = 9.8 m/s2)?

22. the top of a cliff is located a distance h above the ground. at a distance h/2 there is a branch that juts out from the side of the cliff, and on this branch a bird's nest is located. two children throw stones at the nest with the same initial speed, one stone straight downward from the top of the cliff and the other stone straight upward from the ground. in the absence of air resistance, which stone hits the nest in the least amount of time?
