In an apparent effort to earn an appearance on the destroyed in seconds show, caleb attempts a bicycle maneuver in which he jumps between two ramps whose elevated edges are located a distance of 1.8 meters apart. the ramps are angled at 35° and located at the same height. determine the speed (in m/s and mi/hr) that caleb must acquire to accomplish this stunt. (given: 1.00 m/s = 2.24 mi/hr)

Two particles of masses m and 2m are placed on a smooth horizontal table. a string, which joins these two masses, hangs over the edge supporting a pulley, which suspends a particle of mass 3m. the pulley has negligible mass. the two parts of the string on the table are parallel and perpendicular to the edge of the table. the hanging parts of the string are vertical. find the acceleration of the particle of mass 3m.

Find the magnetic field a distance r from the center of a long wire that has radius a and carries a uniform current per unit area j in the positive z direction.
