Consider the mass on aspring system in Figure P11.20. Three identical springs, with the same spring constant k = 65 N/m, are used to connect the mass (m = 28 kg) to the ceiling. What is the frequency of this simple harmonic oscillator?
A 66-N m torque acts on a wheel with a moment of inertia 175 kg m2. If the wheel starts from rest, explain how long will it take the wheel to make one revolution?
"Jerk" is the rate of change of acceleration, and it's what can make you sick on an amusement park ride. Find an expression for the maximum jerk
Suppose a 65 kg person stands at the edge of a 6.5 m diameter merry-go-round turntable that is mounted on frictionless bearings and has a moment of inertia of 1850 kg m2. Calculate the angular velocity of the turntable
A 0.60 kg body oscillates on a spring that, when extended 1.0 mm from equilibrium, has a restoring force of 7.0 N. find the angular frequency of oscillation
A boy drags his 8.00 kg sled at constant speed up a 10.0 degree hill. He does so by pulling with a 40.0-N force on a massless rope attached to the sled. find the coefficient of kinetic friction between sled and snow
A sport utility vehicle (SUV) and a sports car travel around the same horizontal curve. The SUV has a static stability factor of 0.80 and can negotiate the curve at a most speed of 18 m/s without rolling over.
