spring 21.6 Question 2 to a vertical wall such that an object attached to the end of the spring is free to slide orce of 5N, it causes a A spring is mounted on a very smooth horizontal surface. When we pull on the free end of the spring with a f displacement of 1em. Next we attach a 2.5kg object to the relaxe of 4cm, then release it. d spring and push it toward the wall a distance a. Find the force constant of the spring. b. Find the period and frequency of the motion. c. Find the maximum velocity the object will experience

Explanation / Answer

A)

here , spring stretch , x = 1 cm

x = 0.01 m

Now , as Force = k * x

5 = k * 0.01

k = 500 N/m

the spring consant is 500 N/m

b)

Now, frequency of motion is given as

f = sqrt(k/m)/2pi

f = sqrt(500/4)/(2pi)

f = 1.78 Hz

the frequency of motion is 1.78 Hz

Period = 1/f

Period = 1/1.78

Period = 0.562 s

the period is 0.562 s

C)

maximum velocity = 2*pi*f*A

maximum velocity = 0.04 * 2pi*1.78

maximum velocity = 0.447 m/s

the maximum velocity is 0.447 m/s
