Question

(a) the mechanical energy of the system 0.102 (b) the maximum speed of the object 0.638 m/s (c) the maximum acceleration of the object 14.56 Need Help? My Notes Ask Your A vertical spring stretches 4.2 cm when a 6-g object is hung from it. The objectts replaced with a block of mass 26 g that oscilates up and down in simple harmonic motion. Caliculate the period of motion Need Help? e Master Notes Ask Your The sinusoidal wave shown in the figure below is traveling in the positive x-direction and has a frequency of 62.1 Hz 28 ees 9

Explanation / Answer

5) using the hooke's law of elasticity

F = k*x

m*g = k*x

6*10^-3*9.8 = k*0.042

spring constant is k = 1.4 N/m

then now period of motion is T =2*pi/w

w is the angular frequency = sqrt(k/m) = sqrt(1.4/0.026) = 7.34 rad/s

then period is T = 2*pi/w = (2*3.142)/7.34 = 0.856 sec
