Halley's comet moves i all Which of the following best explains why the comet loses speed in this way? Choose 1 answer: The centripetal force exerted on Halley's comet is smaller than the gravitational force exerted on Halley's comet during this portion of the orbit. As Halley's comet recedes from the sun, the Sun-comet system gains potential energy, and Halley's comet loses kinetic energy. The Sun exerts a torque on Halley's comet during its motion about the sun and decreases the Sun-comet system's angular momentum. A component of the gravitational force on Halley's comet is perpendicular to its direction of motion, causing the comet to lose speed.

Fast pls solve this question correctly in 5 min pls I will give u like for sure Rafe Two stock cars of equal mass 2920 kg are racing on a track. The cars are required to navigate a turn banked at an angle 11° with respect to the horizontal axis. The banked turn has a radius of curvature, 232 m. There is a coefficient of static friction between the tires and the road of μs = 0.61. The cars can drive at a speed of vmax without slipping towards the wall (without overcoming the static friction between the tires and the road). While driving through the banked turn, the car in front is driving at a speed of v1i = 33.9 m/s. The car in back, which is travelling at a speed of v2i = 38.1 m/s, squarely rear ends the back of the first car in a perfect elastic collision. 1.What is the maximum speed, vmax, the cars can take on this banked curve? 2.After the collision, what is the speed of the first car, v1f? 3.After the collision, what is the speed of the second car, v2f? 4.After the…
