A person drives a car around a circular, level cloverleaf with a radius of 70 m at a uniform speed of 10 m/s. (a) What is the acceleration of the car? (b) Compare this answer with the acceleration due to gravity as a percentage. Would you be able to sense the cars acceleration if you were riding in it?
A projectile is fired vertically from point A with an initial speed of 215 ft/sec. Relative to an observer located at B, at what times (find two times t1 < t2) will the line of sight to the projectile make an angle of 23° with the horizontal? Compute the magnitude of the speed of the projectile at each time, and ignore the effect of aerodynamic drag on the projectile. Calculate the height h when the projectile is at point C.
An archer fish spies a meal of a grasshopper sitting on a long stalk of grass at the edge of the pond in which he is swimming. The fish is to successfully spit at and strike the grasshopper, which is 0.200 m away horizontally and 0.435 m above his mouth. What angle (in degrees) above the horizontal must he spit? Assume vfy = 0.
A swimmer heads directly across a river, swimming at 1.10 m/s relative to still water. He arrives at a point 50.0 m downstream from the point directly across the river, which is 75.0 m wide. What is the speed of the river current?What is the swimmer's speed relative to the shore? In what direction should the swimmer head so as to arrive at the point directly opposite his starting point? Express your answer in terms of the angle with respect to a line drawn directly across the river.
An archer fish spies a meal of a grasshopper sitting on a long stalk of grass at the edge of the pond in which he is swimming. The fish is to successfully spit at and strike the grasshopper, which is 0.200 m away horizontally and 0.395 m above his mouth. A) What angle (in degrees) above the horizontal must he spit? (In degrees)
A projectile is Fİred with a speed v0 due south from a gun located at a latitude THETA in thenorthern hemisphere on the earth's surface. The initial angle that the projectile makeswith the horizontal is BETA . Find the correction to the point of impact due to the Coriolisforce.
A small, experimental aluminum airplane leaves its classified location on a foggy and overcast day, and flies at 198 km/h (= 55.0 m/s), at a constant height h of 500 m, toward a point directly over a victim of a bizarre, classified experiment, floating in a remote mountain lake, where a rescue capsule is to land. (a) What should be the angle φ of the alien pilot’s line of sight to the victim when the capsule release is made? (b) As the capsule reaches the water, what is its velocity ⃗v?
A military cargo plane is passing over a remote area of wilderness where it cannot make a safe landing. instead of landing the cargo it's dropped. The plane is flying at 284m/s horizontally at an altitude of 584m. How far out in front of the landing target should the cargo be let out the back of the plane?
An airplane flies horizontally above the flat surface of a desert at an altitude of 5 km and a speed of 915 km/h. If the airplane is to drop a care package that issupposed to hit a target on the ground, where should the plane be with respect to the target when the package is released? (Enter the horizontal distance between theplane and the target.) If the target covers a circular area with a diameter of 45 m, what is the "window of opportunity" (or margin of error allowed) for the release time?
A science student is riding on a flatcar of a train traveling along a straight, horizontal track at a constant speed of 10.0 m/s. The student throws a ball into the air along a path that he judges to make an initial angle of 60.0° with the horizontal and to be in line with the track. The student’s professor, who is standing on the ground nearby, observes the ball to rise vertically. How high does she see the ball rise?
A pirate ship is 506 m away from a fort that is being defended by artillery that is sea level. The defensive cannon is capable of firing a cannon ball at 95 m/s. At what angle(s) above horizontal can the cannon fire the cannon ball so that it will hit the pirate ship?
A fire hose held near the ground shoots water at a speed of 5.9 m/sm/s. At what angle(s) should the nozzle point in order that the water land 2.5 mm away? Express your answer(s) in degrees to two significant figures. If there is more than one answer, separate them by a comma.
