We are presented with a particle of mass (m = 4.56 kg) which is in uniform circular motion going around a fixed point O. It had a radius of orbit (r = 3.63 m) and it experiences a net force of magnitude F = Br toward the fixed point O, where B = 2.75 Nm. What is the period of the particles orbit?
Derive expressions for the velocity (~v) and acceleration (~a) vectors in spherical coordinates.That is, transform ~v and ~a from the Cartesian system of (x, y, z) to (r, θ, φ).
Assume that, at the initial instant to = 0, a particle is thrown with initial speed vo and with an initial angle θo, with respect to a direction parallel to the Earth's surface. In this way, in order to carry out an analytical study of its motion in a simpler way, consider a coordinate system xoy, with its origin at the particle's launch position, and with its positive x axis oriented in the direction of the horizontal motion of the particle and with its positive y-axis oriented vertically upward. In this sense, illustrate (make the force diagrams) the projectile launch, highlighting its main characteristics, and describe algebraically what is asked:

A jet is flying at 120 m/s along a straight line and makes a turn along a circular path level with the ground, remaining at a constant speed. What must be true about the radius R of the circular path if the turn produces a centripetal acceleration of less than 2g on the pilot and jet?
An ice skater is executing a figure-eight, consisting of two identically shaped, tangent circular paths. Throughout the first loop, she increases her speed uniformly, and during the second loop she moves at a constant speed. When the ice skater travels during the first loop, the acceleration vector is not directed towards the center, whereas when the ice skater travels in the second loop, the acceleration vector is directed toward the center. Is this true or false?

Does your answer imply that error introduced by the assumption of a flat earth in projectile motion is significant here?
