The angular position of a pendulum is represented by the equation u = 0.032 0 cos vt, where u is in radians and v = 4.43 rad/s. determine the period and length of the pendulum.

The period, T = 1.4183 seconds, and

the length of the pendulum, L = 0.5 meters

Explanation:

Formula for period T = 2π/v

Where π = 3.1416

velocity of pendulum, v = 4.43 rad/s

Therefore, T = 2 × 3.1416/4.43 = 1.4183 seconds

Formula for length of a pendulum, L = g/v²

Where g = 9.81 m/s²

v = 4.43 rad/s

Therefore, L = 9.81/4.43² = 0.5 meters.

the answer is c.)

explanation:

a longitudinal wave moves energy that is to the direction of the wave’s movement. - true
