The cern particle accelerator is circular with a circumference of 7.0 km.
(a) what is the acceleration of the protons (m = 1.67 × 10−27 kg) that move around the accelerator at 5% of the speed of light? (the speed of light is v = 3.00 × 108 m/s. )
(b) what is the force on the protons?

Most short-period comets do not have randomly oriented orbits because

Two students, each riding bicycles, start from the same apartment building and ride to the same building on campus, but each takes a different route. the first student rides 1100 m due east and then turns due north and travels another 1430 m before arriving at the destination. the second student heads due north for 1930 m and then turns and heads directly toward the destination.at the turning point, how far is the second student from the destination?

Acar travels in reverse. it covers 150 meters in 12 seconds what is the velocity of the car what is the speed of the car
