A motorcycle rider is moving at a speed of 2 m/s. He then decides to accelerate his bike at a rate of 3 m/s^2 for a distance of 100 m. How fast is the bike moving at the end of the 100 m stretch? I am a little confused with this so if you could show me how you got it that would be great thank you!

Aball has an initial velocity of 3 m/s. if there is no friction, what is the highest it could roll?

Ametal ring 4.20 cm in diameter is placed between the north and south poles of large magnets with the plane of its area perpendicular to the magnetic field. these magnets produce an initial uniform field of 1.12 t between them but are gradually pulled apart, causing this field to remain uniform but decrease steadily at 0.240 t/s . (a) what is the magnitude of the electric field induced in the ring? (b) in which direction (clockwise or counterclockwise) does the current flow as viewed by someone on the south pole of the magnet?

What energy transformations occur each time the skateboarder rolls up the ramp?
