In Figure below, a charged particle moves into a region of uniform magnetic field , goes through half a circle, and then exits that region. The particle is either a proton or an electron (you must decide which). It spends 108 ns in the region. (a) What is the magnitude of ? (b) If the particle is sent back through the magnetic field (along the same initial path) but with 4.84 times its previous kinetic energy, how much time does it spend in the field during this trip?
A dockworker applies a constant horizontal force of 71.0 to a block of ice on a smooth horizontal floor. The frictional force is negligible. The block starts from rest and moves a distance 11.5 in a time 5.00 . what is the mass of the ice block?
What is the initial velocity of Block B, constant acceleration of Block A, velocities of both blocks at t=3s, and the total distance traveled by block B from t=0s to t=3s?
Use calculus to obtain a closed-form solution for the case where the parachutist jumper is initially at rest (v=0 at t=0) to solve F(upward)= -cv^2, where c = a second-order drag coefficient (kg/m).
