where c is the wave speed and f is the frequency
Answer:
Distance is 800 m and Displacement is 0 m
Explanation:
Total Distance
= 400(2)
= <u>800</u><u> </u><u>m</u>
Total Displacement
= <u>0</u><u> </u><u>m</u> since she returns to the same spot
Answer:
Kinetic energy
Explanation:
Kinetic energy is a function of velocity. Since the rider is moving at a certain speed, he's demonstrating kinetic energy. It can't be potential energy because potential energy encompass mgh
