Question

A 0.155 kg toy is undergoing SHM on the end of a horizontal spring with force constant 304 N/m. When the object is 1.50 A 0.155 kg toy is undergoing SHM on the end of a horizontal spring with force constant 304 N/m. When the object is 1.50 A 0.155 kg toy is undergoing SHM on the end of a horizontal spring with force constant 304 N/m. When the object is 1.50times10? 2m from its equilibrium position, it is observed to have a speed of 0.320 m/s find total energy of object at any point in motion find amplitude of motion  find max speed attained by object during its motion

Explanation / Answer

a) E = 0.5*k*x^2 + 0.5*m*v^2

= 0.5*304*1.5^2*10^-4 + 0.5*0.155*0.32^2

= 0.042136 J

b) E = 0.5*k*A^2

A = sqrt(2*E/k)

= sqrt(2*0.042136/304) = 1.665*10^-2 m

C) E = 0.5*m*v^2

v = sqrt(2*E/m)

= sqrt(2*0.042136/0.155) = 0.737 m/s
