Two ducks, Donald and Cassiopeia, are gliding gracefully toward eachother along a pond, in a straight line. Donald is initially moving at v =0.500 m/s, and begins accelerating at 0.100 m/s2 at t = 0 s. Cassiopeiamoves at a constant speed of v = 0.700 m/s. If they are initially separatedby 25.0 m, where will they collide? Take Donald’s initial position as theorigin. How long will it take for them to collide?
An inquisitive physics student and mountain climber climbs a 51.0-m-high cliff that overhangs a calm pool of water.

In the blizzard of ’88, a rancher was forced to drop hay bales from an airplane to feed her cattle. The plane flew horizontally at 160 km/hr and dropped the bales from a height of 80 m above the flat range, (a) She wanted the bales of hay to land 30 m behind the cattle so as to not hit them. Where should she push the bales out of the airplane? (b) To not hit the cattle, what is the largest time error she could make while pushing the bales out of the airplane? Ignore air resistance.

A ball is thrown straight up from the edge of the roof of abuilding. A second ball is dropped from the roof 1.00 s later. Ignoreair resistance. (a) If the height of the building is 20.0 m, what must theinitial speed of the first ball be if both are to hit the ground at the sametime? On the same graph, sketch the positions of both balls as a functionof time, measured from when the first ball is thrown. Consider thesame situation, but now let the initial speed v0 of the first ball be givenand treat the height h of the building as an unknown. (b) What mustthe height of the building be for both balls to reach the ground at thesame time if (i) v0 is 6.0 m/s and (ii) v0 is 9.5 m/s ? (c) If v0 is greaterthan some value vmax, no value of h exists that allows both balls to hitthe ground at the same time. Solve for vmax. The value vmax has a simplephysical interpretation. What is it? (d) If v0 is less than some value vmin,no value of h exists that allows both balls to hit the ground at the…
A ball is thrown straight up. It passes a 2.00-m-highwindow 7.50 m off the ground on its path up and takes 0.312s to go past the window. What was the ball’s initial velocity?Hint: First consider only the distance along the window, andsolve for the ball's velocity at the bottom of the window. Next,consider only the distance from the ground to the bottom ofthe window, and solve for the initial velocity using the velocityat the bottom of the window as the final velocity.
