The Raptor is an outside loop roller coaster in which riders are belted into seats resembling ski-lift chairs.
1. Draw the free body diagram of the rider at the highest position in the loop.
2. Calculate using the work and energy method, the velocity v1 of the rider at the highest position in the loop.
3/ Determine the minimum speed v0 at which the seat should coast down from the top of the hill, so that passengers can just make the loop without leaving contact with their seats.
Two small charges with a mass of 1.0 g each are connected by 2.0-cm-long insulating rod of negligible mass. What is the dipole moment of the rod?

A robber's getaway vehicle, which can travel at 0.8c, is pursued by a cop. whose vehicle can travel at 0.4c. Realizing that he cannot catch up with the robber, the cop tries to shoot him with bullets that travel at 0.5c (relative to the cop). Can the..
Suppose a bullet of mass m = 6.77g is fired into a ballistic pendulum whose bob has a mass of M = 0.693kg. What was the speed of the bullet-bob combination immediately after the collision takes place
a straight wire in a magnetic field experiences a force of 0.034 n when the current in the wire is 2.5 a. the current
A force of k is applied to an object for a small fraction of a second, t_k, less than the duration of one frame, t_f. Our simulation doesn't support applying forces for less than an entire frame, so if we wanted to simulate the effect of force k over..
