5. A wagon, initially traveling at a constant 1.5 m/s, starts going down a hill that creates an acceleration of 1.0 m/s. What is the wagon's velocity 2.8 s after it starts accelerating
down the hill?

Abeam of electrons moves at right angles to a magnetic field of 4.5 × 10-2 tesla. if the electrons have a velocity of 6.5 × 106 meters/second, what is the force acting on the electrons? the value of q = -1.6 × 10-19 coulombs.
