Answer:
3 Cycles
Explanation:
Every cycle on a cosine function are marked by the completion of 5 key points when moving along the x-axis:
(5, 0, -5, 0, 5)
This cycle has a frequency of 2, occurring once every second, thus answering our question easily.
Answer:
a) 11.21 m/s
b) 513.89 N
Explanation:
mass of addict = 77 kg
radius of circle= 10 m
velocity of circular motion v =5.6 m/s
a)time period of motion
T= 2πr/v = 2×3.14×10/5.6 = 11.21 sec
b) At the highest point normal reaction force F_N is upward
the gravitational force F_g is downward and centripedal force mv^2/r is upward
F_N= F_g - mv^2/r
= 77*9.81- 77*5.6^2/10
= 513.89 N
