If the time for 20 vibrations is 100 second then find
1: time period
2: frequency
plzz answer me i am so confused

Explanation:

It is given that,

Number of vibrations, N = 20

Time taken, t = 100 s

2. The total number of vibrations per unit time is called the frequency of the object. It is given by :

f = 0.2 Hz

1. The reciprocal of the frequency of the particle is called its time period. It is given by :

T = 5 seconds

Hence, this is the required solution.

answer: 31, 5556. 952 seconds

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
