A motorcycle with a mass of 100 kg travels around a flat, circular track with a radius of 10m with a constant speed of 20m/s. a. What type of centripetal force is keeping the motorcycle moving on the path?

b. What is the magnitude of the force required to keep the motorcycle moving in a circular path at this speed?

The image shows a pendulum in simple harmonic motion the pendulum starts at a and swing to e

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.

Two objects of different mass start from rest, are pulled by the same magnitude net force, and are moved through the same distance. the work done on object 1 is 900 j. after the force has pulled each object, object 1 moves twice as fast as object 2. how much work is done on object 2?
