An object attached to a horizontal spring is oscillating back and forth along a frictionless surface. the maximum speed of the o
Andreas93 [3]
<span>First of all, the maximum speed occurs when the object passes through the
 equilibrium position

The kinetic energy when the object has this max speed is

K= 1/2 * mass * (1.25 m/s)^2

The potential energy in the spring when the speed is equal to zero

U= 1/2 * k * xmax^2

The maximun force of the spring is

mass*acceleration = k*xmax

m * 6.89 m/s2 = k * xmax
xmax = 6.89* m / k

0.5 * m * 1.56  = 0.5 * k * xmax^2

</span>m * 1.56  =  k * (<span>6.89* m / k )^2 </span>
<span>
1.56 m = 47.47 m^2 / k
m/k = 0.032862

period = 2 *pi*sqrt[m/k]
= 2 pi </span><span>sqrt [ </span><span>0.032862]
= 1.139  s

  A fourth of the period elapses between the instants of max acceleration and maximum speed

= 1/4* period

Find the frequency if the period is 15 us.
Sav [38]

Answer:

The frequency is 0.667× 10^{6} Hz.

Explanation:

  1. Period is defined as the time taken by any element to attempt one complete oscillatory motion in one second.
  2. Frequency is the number of complete oscillations made in one second.
  • Frequency and period are inversely proportional to each other.
  • In mathematical term: frequency = \frac{1}{period}.
  • As we are given, period = 15×10^{-6} s.
  • We can easily calculate frequency as: f\\= \frac{1}{15. 10^{-6} }
  • So frequency is f= 0.667× 10^{6} Hz.
