- A projectile is fired at the edge of a cliff, with initial an velocity of 12.0 m/s at an angle of 40.0 degrees. If it takes the projectile 10.0 s to land on the bottom of the cliff, how high is the cliff? 482 m O none of the given choices 41.3 m 370. m 398 mAfter flying for 18 min in a wind blowing 38 km/h at an angle of 22° south of east, an airplane pilot is over a town that is 57 km due north of the starting point. What is the speed of the airplane relative to the air?An airplane pilot wishes to fly due west. A wind of 72.0 km/hkm/h is blowing toward the south. If the airspeed of the plane (its speed in still air) is 305.0 km/hkm/h, in which direction should the pilot head? Express your answer in degrees. What is the speed of the plane over the ground? Express your answer in kilometers per hour.
- A player throws a ball towards a high wall. The ball leaves the player's hand at a height of 2 meters above the ground with a velocity of 5.00 m/s at an angle of 30°. The wall is at a horizontal distance 4.00 meters away from the player. At what height above the ground will the ball hit the wall? Wall Y=2 m X=4 mAt the equator, the radius of the Earth is approximately 6370km. A jet flies at a very low altitude at a constant speed of v=237m/s. Upon landing, the jet can produce an average deceleration of magnitude a=21.5m/s^2. A. How long, in seconds, will it take the jet to circle the Earth at the equator? B. What is the minimum landing distance, in meters, this jet needs to come to rest? Assume that, when the jet initially touches the ground, it is moving at the same speed as it was when it was flying.An airplane traveling horizontally 1600 m above the ocean at 68.2 m/s must drop a box of rescue supplies to sailors stranded on a remote island. 3. How many seconds before being directly above the sailors should the pilot release the box of rescue supplies? (Air resistance is negligible.) a. Time = b. Given the drop time above, what is the horizontal distance between the airplane and the stranded sailors when the box of rescue supplies must be released? (Air resistance is negligible.) Distance =
- 7. A projectile is shot from the edge of a cliff 150 m above ground with an initial speed of 65.0 m/s at an angle of 26° above the horizontal. How much time it take the projectile to hit the ground? seconds 50 ssf60° 50 ssf6s ssf60 ssf6ð f60 ssIn an attempt to escape his island, Gilligan builds a raft and sets to sea. The wind shifts a great deal during the day, and he is blown along the following straight lines: 2.5 km 45° north of west; then 4.70 km 60° south of east; then 5.1 km straight east; then 7.2 km 55° south of west; and finally 2.8 km 10° north of east. What is his final position relative to the island? km ° south of eastThere is a tree in the middle of your front yard and you take pictures of a squirrel as it runs around the tree. When you take the first picture, the squirrel is 12.0 m away from the tree in the direction 30.0° N of E. Twenty seconds later, you take a second picture of the squirrel when it is 7.50 m away from the tree in the direction 15.0° E of S. What is the magnitude and direction of the average velocity of the squirrel between the two pictures?
- A ship sets sail from Rotterdam, The Netherlands, heading due north at 5.00 m/s relative to the water. The local ocean current is 1.54 m/s in a direction 40° north of east.
