- Pt. d&eA ship sets sail from Rotterdam, heading due north at 7.00 m/s relative to the water. The local ocean current is 1.50 m/s in a direction 40.0° north of east. What is the velocity of the ship relative to Earth?A vessel sets out from Delfzijl, The Netherlands, heading due north at 9.5 m/s relative to the water. The local ocean current is 1.50 m/s in a direction 40.0° north of east. What is the angle of the velocity of the vessel relative to the Earth in degrees N of E?
- An artillery shell is fired with an initial velocity of 300 m/s at 54.5° above the horizontal. To clear an avalanche, it explodes on a mountainside 34.0 s after firing. What are the x- and y-coordinates of the shell where it explodes, relative to its firing point? x=? y=?I need help on this problem: A pipe discharges storm water into a creek. Water flows horizontally out of the pipe at 1.9m/s, and the end of the pipe is 3.5m above the creek. How far out from the end of the pipe is the point where the stream of water meets the creek? Express your answer with the appropriate units.A pilot starting from Athens, New York, wishes to fly to Sparta, New York, which is 381 km from Athens in the direction 22° N of E. The pilot heads directly for Sparta and flies at an airspeed of 151 km/h. After flying for 2.52 h, the pilot expects to be at Sparta, but instead he finds himself 16 km due west of Sparta. He has forgotten to correct for the wind. (a) What is the velocity of the plane relative to the air? (b) Find the velocity (magnitude and direction) of the plane relative to the ground. (c) Find the wind speed and direction. Please be thorough.
- You are standing on a cliff overlooking a lake and decide to throw a softball to your friends in the water below. You throw the softball with a velocity of 19.5 m/s at an angle of 38.5 degrees above the horizontal. When the softball leaves your hand it is at 13.5m above the water. How far does the softball travel horizontally before it hits the water? Neglect any air effects of Air resistanceA hunter spots a duck flying a given distance, h, above the ground (in meters) and shoots at it with his shotgun. The buckshot leaves the shotgun at an angle equal to 57.7 degrees from the horizontal with a velocity of 105 m/s. The duck is flying at a speed of 30 m/s in a horizontal direction toward the hunter. If the hunter shot when the duck was 200 meters away from the hunter and hit the duck, how high was the duck flying?An arrow is shot from a height of 1.6m toward a cliff of height H. It is shot with a velocity of 27 m/s at an angle of 60 above the horizontal. It lands on the top edge of the cliff 3.8s later. a ) what is the height of the cliff (in m)? b) what is the maximum height (in m) reached by the arrow along its trajectory? c) what is the arrows impact speed in m/s just before hitting the cliff ?
- A jetliner can fly 6.8 hours on a full load of fuel. Without any wind it flies at a speed of 3.24 x 10² m/s. The plane is to make a round-trip by heading due west for a certain distance, turning around, and then heading due east for the return trip. During the entire flight, however, the plane encounters a 75.9-m/s wind from the jet stream, which blows from west to east. What is the maximum distance (in kilometers) that the plane can travel due west and just be able to return home? Number Units ◄►Two cars approach each other at an intersection. Car A is traveling south at 30 m/s, while car B is traveling 70 degrees north of east at 50 m/s. What is the speed (in m/s) of car A as seen by the driver of car B?A projectile is fired from the edge of a cliff, with an initial speed of 185 m/s at an angle of 40.0° above the horizontal. The projectile rises and then falls into the sea next to the cliff. The height of the cliff measured from the sea level is h. The time of flight of the projectile until it hits the water is 40.0 s. Ignore air resistance. What is the height h of the cliff? What is the maximum height the projectile has reached (measured from the seal level)? What is the magnitude of the ball's velocity just before it hits the ground?
