A jet pilot takes his aircraft in a vertical loop , if the jet is moving at a speed of 1140 km/m , at the lowest point of the loop , determine the minimum radius (r) of the circle , so that the centripetal acceleration at the lowest point doesn't exceed 6.4 g's please pay attention , previously you sent the answer , but that was not correct , that's why i am sending again

A ball on the end of a string is whirled around in a horizontal circle of radius 0.254 m. The plane of the circle is 1.31 m above the ground. The string breaks and the ball lands 2.16 m away from the point on the ground directly beneath the ball’s location when the string breaks. The acceleration of gravity is 9.8 m/s2 . Find the centripetal acceleration of the ball during its circular motion.

Learning Goal: To find some of the parameters characterizing an object moving in a circular orbit. The motivation for Isaac Newton to discover his laws of motion was to explain the properties of planetary orbits that were observed by Tycho Brahe and analyzed by Johannes Kepler. A good starting point for understanding this (as well as the speed of the space shuttle and the height of geostationary satellites) is the simplest orbit: a circular one. This problem concerns the properties of circular orbits for a satellite orbiting a planet of mass M. For all parts of this problem, where appropriate, use G for the universal gravitational constant. The potential energy U of an object of mass m that is separated by a distance R from an object of mass M is given by U=-G Mm R What is the kinetic energy K of the satellite? Express your answer in terms of the potential energy U. K = Submit Part D T = Find the satellite's orbital period T. Express your answer in terms of G, M, R, and T. ► View…

An accelerometer C is mounted to the side of the roller-coaster car and records a total acceleration of 3.3g as the empty car passes the bottommost position of the track as shown. If the speed of the car at this position is 195 km/h and is decreasing at the rate of 22 km/h every second, determine the radius of curvature p of the track at the position shown. Answer: p-i I ! m 0.73 m

A race car rounds a curve at 54 m/s. The radius of the curve is 428m, and the car's mass is 630 kg. Assume the car's speed remains constant. Take the radially inward direction to be positive. Indicate the direction with the sign of your answer. what is the car's centripetal acceleration?  what is it in g's?  what is the centripetal force acting on the car?

A BMX biker wanted to impress his family by catching some air( aka leaving the ground) while riding over a hill in Tennesse with a radius of curvature of 7.6m. If the BMX biker rides over the hill at 11.2 m/s, will she catch some air and excitee her family?  B) What is the minimum speed the biker has to travel in order to leave the ground when cresting the hill?

A fairground ride spins its occupants inside a flying saucer-shaped container. If the horizontal circular path the riders follow has a 4.33 m radius, if the riders is subjected to a centripetal acceleration 3.5 times that due to gravity, what is the spinning speed in unit of revolutions per minute? Use g = 9.8 m

A race car goes around a level, circular track with a radius of 22 meters at a constant speed of 39.6 m/s.(a) What is the car's centripetal acceleration?
