2. Colliding marbles The accompanying figure shows an experi- ment with two marbles. Marble A was launched toward marble B with launch angle a and initial speed vo. At the same instant, marble B was released to fall from rest at R tan a units directly above a spot R units downrange from A. The marbles were found to collide regardless of the value of vọ. Was this mere coincidence, or must this happen? Give reasons for your answer. B

A clod of dirt falls from the bed of a moving truck. It strikes the ground directly below the end of the truck. What is the direction of its velocity relative to the truck just before it hits? Is this the same as the direction of its velocity relative to ground just before it hits? Explain your answers.
A soccer goal is 2.44 m high. A player kicks the ball at a distance 10 m from the goal at an angle of 25 . The ball hits the crossbar at the top of the goal. What is the initial speed of the soccer ball?
Suppose the airplane in the preceding problem fires a projectile horizontally in its direction of motion at a speed of 300 m/s relative to the plane. (a) How far in front of the release point does the projectile hit the ground? (b) What is its speed when it hits the ground?
An object is shot horizontally off a cliff which is 19.95 meters high. The forward speed when it is fired is 6.321. How far forward from the firing point does it land? (Your answer should be in meters, but don't write the unit; just the nuumber.) Use the acceleration due to gravity near the earth's surface, g=10m/s^2 (Remember that the horizontal and vetical motion can be treated seperately, so you can first find the time of flight, then figure out how far foward it moves in that time)
Time of motion is 5 seconds, I cant find the last two colubs
As a science project, you drop a watermelon off the top of the Empire State Building, 320m above the sidewalk. It so happens that Superman flies by at the instant you release the watermelon. Superman is headed straight down with a speed of 33.0 m/s How fast is the watermelon going when it passes Superman?
A baseball player hits a homerun during a game. The ball leaves his bat at 27 degrees with a speed of 17 m/s. The ball soars into the upper deck 200 m from home plate. How far, from the batter, will the ball travel if there were no bleachers?
An airplane used to drop water on brushfires is flying horizontally in a straight line at 315 km/hat an altitude of 80m. Determine the distance and the direction at which the pilot should releasethe water so that it will hit the fire at the ground. What is the time elapsed of the first drop ofwater on the ground?
A baseball leaves the hand of a pitcher 6 vertical feet above and 60 horizontal feet from homeplate. Assume the coordinate axes are such that the origin is at ground level directly below the point ofrelease. Suppose a pitch is thrown with an initial velocity of < 130,0,−3 > ft/s (i.e. about 90 mph).In the absence of all forces except gravity, how far above the ground is the ball when it crosses homeplate and how long does it take the pitch to arrive?
A basketball player passes the ball to a teammate who catches it 11 ft above the court, just above the rim of the basket, and slam-dunks it through the hoop. (This play is called an “alley-oop.”) The first player releases the ball 5 ft above the court with an initial vertical velocity of 21 ft/sec. How long is the ball in the air before being caught, assuming it is caught as it rises?
