Answer:
0.230 s
Explanation:
The period is the length of time from one peak to the next. If it takes the oscillator 0.115 s to go from the lowest point to the highest point, then it takes another 0.115 s to return to the lowest point. So the period is 0.115 + 0.115 = 0.230 seconds.
Answer:
217.28 m/s
Explanation:
u = 0, t 32.3 s, v = 47.1 m/s, s = 607 m
Let a be the acceleration.
Use third equation of motion.
v^2 = u^2 + 2 a s
47.1 x 47.1 = 0 + 2 a x 607
a = 1.83 m/s^2
For small plane
a = 1.83 m/s^2 , v = 28.2 m/s, u = 0, Let teh distance be s.
Use third equation of motion
28.2^2 = 0 + 2 x 1.83 x s
s = 217.28 m/s
