A dart gun is fired while being held horizontally at a height of 1.00 m above ground level and while it is at rest relative to the ground. The dart from the gun travels a horizontal distance of 5.00 m. A college student holds the same gun in a horizontal position while sliding down a 45.0 incline at a constant speed of 2.00 m/s. How far w ill the dart travel if the student fires the gun when it is 1.00 m above the ground?
David Beckham has lined up for one of his famous free kicks from a point 25.0 m from the goal. He kicks the soccer ball with a speed of 22.0 m/s at 28.0 to the horizontal. The height of the goals crossbar is 2.44 m. a. What is the distance from the crossbar with which the ball will go into the goal or sail over? b. Does the soccer ball reach the goal on its way up or on its way down?
A Nordic jumper goes off a ski jump at an angle of 10.0 below the horizontal, traveling 108 m horizontally and 55.0 m vertically before landing. (a) Ignoring friction and aerodynamic effects. calculate the speed needed by the skier on leaving the ramp. (b) Olympic Nordic jumpers can make such jumps with a jump speed of 23.0 m/s, which is considerably less than the answer found in pan (a). Explain how that is possible
The Vomit Comet. In microgravity astronaut training and equipment testing, NASA flies a KC135A aircraft along a parabolic flight path. As shown in Figure P4.59, the aircraft climbs from 24 000 ft to 31 000 ft, where it enters a parabolic path with a velocity of 143 m/s nose high at 45.0 and exits with velocity 143 m/s at 45.0 nose low. During this portion of the flight, the aircraft and objects inside its padded cabin are in free fall; astronauts and equipment float freely as if there were no gravity. What are the aircrafts (a) speed and (b) altitude at the top of the maneuver? (c) What is the time interval spent in microgravity?

(b) If the bird turns around and flies with the wind, how long will he take to return 6.00 km? (c) Discuss how the wind affects the total round-trip time compared to what it would be with no wind.
A spring cannon is located at the edge of a table that is 1.20 m above the floor. A steel ball is launched from the cannon with speed vi at 35.0 above the horizontal. (a) Find the horizontal position of the ball as a function of vi at the instant it lands on the floor. We write this function as x(vi). Evaluate x for (b) vi = 0.100 m/s and for (c) vi = 100 m/s.

You are standing 18.0 meters away from a building, which is 15.0 meters tall and has a large, flat roof. You throw a baseball with an initial speed of 22.5 meters per second, at an angle of 55.0 degrees above the horizontal. When the baseball leaves your hand, it is 1.5 meters above the ground. The baseball lands on the roof of the building. (a) How long is the baseball in the air before landing on the roof (in seconds)?
