A longitudinal wave is a wave in which particles of the medium move in a direction parallel to the direction that the wave moves
Answer:
0 m/s
Explanation:
Average velocity is displacement over time.
v_avg = Δx / Δt
Displacement is the distance between the start and the finish.
The circumference of the track is:
C = 2πr
C = 2π (7 m)
C ≈ 44 m
The distance covered by the object is:
d = vt
d = (11 m/s) (8 s)
d = 88 m
So the object travels 2 circumferences, meaning it ends back where it started. Therefore, the displacement is 0 m, and the average velocity is 0 m/s.
Answer:
Explanation:
According to Newton's second law, we have:
The force of friction is opposite to the motion of the block.
Using the following kinematic equation, we can calculate the distance traveled by the block before it stops().
Solving for x and replacing a from (1):
Answer:
Explanation:
As we know that the ball is swinging in a circle
so here net horizontal centripetal force on the ball is due to component of the tension force
so we will have
also we know that
so we have
now we have
now we have
