A small object goes down a ramp and through a loop with a 2 metre diameter. In order to complete the loop, what is the minimum speed the object must have when reaching the bottom of the ramp? (consider there is no friction) a) 5 m/s b) 0 m/s c) 3 m/s d) 7 m/s I'm a bit clueless on...

if for example n = 1, the angle would be 3pi/2. do you agree?

I have written absolutely everything that they gave me, I'm also finding it impossible to solve this problem.

a particle A has a circular movement with radius R and angular velocity of 2w, a particle B has a radius of 2R and an angular velocity of w, both velocities remain constant. particle B rotates clockwise and particle A rotates anticlockwise for an interval of t = n/(2w) what angle is formed by...
