A 2.0-kg block on a frictionless table is connected to two springs whose opposite ends are fixed to walls,as shown in the figure.The springs have force constants (spring constants)k1 and k2.What is the oscillation angular frequency of the block if
A 92-kg man climbs into a car with worn out shock absorbers,and this causes the car to drop down 4.5 cm.As he drives along he hits a bump,which starts the car oscillating at an angular frequency of 4.52 rad/s.What is the mass of the car?
An object attached to an ideal spring oscillates with an angular frequency of 2.81 rad/s.The object has a maximum displacement at t = 0.00 s of 0.232 m.If the force constant (spring constant)is
What is the potential energy stored in the mass-spring system when t = 1.42 s?
A block attached to an ideal spring of force constant (spring constant)15 N/m executes simple harmonic motion on a frictionless horizontal surface.At time t = 0 s,the block has a displacement of -0.90 m,a velocity of -0.80 m/s,and an acceleration of +2.9 m/s2 .The mass of the block is closest to
