Question

A spring stretches 5.0 cm when a 0.2 kg block is hanging from it. If a 0.7 kg block replaces it, how far does it stretch? What is the frequency of oscillations of he 0.7 kg block if it undergoes SHM? A spring stretches 5.0 cm when a 0.2 kg block is hanging from it. If a 0.7 kg block replaces it, how far does it stretch? What is the frequency of oscillations of he 0.7 kg block if it undergoes SHM? If a 0.7 kg block replaces it, how far does it stretch? What is the frequency of oscillations of he 0.7 kg block if it undergoes SHM?

Explanation / Answer

mg = kx

0.2*9.8 = k*5x10^-2

k = 39.2 N/m

0.7 kg is hanged

mg = kx

0.7*9.8 = 39.2*x

x = 0.175 m

x = 17.5 cm

b) w = sqrt(k/m)

w = 7.4833

f = w/2pi = 1.191 Hz
