A torque of 12 N*m is applied to a solid, uniform disk of radius 0.50m. If the disk accelerates at 2.7rad/s^2, what is the mass of the disk?
A 93.0 kg bungee jumper jumps off a bridge and undergoes simple harmonic motion. If the period of oscillation is 11.2 s, what is the spring constant of the bungee cord?
The howler monkey is the loudest land animal and can be heard up to a distance of 5.5 km. Assume the acoustic output of a howler to be uniform in all directions. The acoustic power emitter by the howler, in mW, is closest to:
A 0.064 kg block on a horizontal frictionless surface is attached to a spring whose force constant is 330 N/m. The block is pulled from its equilibrium position at x=0m to a displacement x=+0.080m and is released from rest. The block then executes simple harmonic motion along the x-axis (horizontal). The velocity of the block at a time t=0.20s is closest to:
