At an outdoor market, a bunch of bananas attached to the bottom of a vertical spring of force constant 16.0 N/m is set into oscillatory motion with an amplitude of 20.0 cm. It is observed that the maximum speed of the bunch of bananas is 40.0 cm/s. What is the weight of the bananas in newtons?

A 0.500-kg mass is suspended from a string, forming a pendulum. The period of this pendulum is 1.58 s when the amplitude is 1.00 cm. The mass of the pendulum is now reduced to 0.250 kg. What is the period of oscillation now, when the amplitude is 2.00 cm?

An astronaut oscillates on a 4400 n/m spring at a frequency of 1.1 hz and amplitude of .23 m. What is the mass of the astronaut?

The period of oscillation of a spring-and-mass system is 0.570 s and the amplitude is 4.44 cm. What is the magnitude of the acceleration at the point of maximum extension of the spring?

A spider can tell when its web has captured, say, a fly because the fly's thrashing causes the web threads to oscillate. A spider can even determine the size of the fly by the frequency of the oscillations. Assume that a fly oscillates on the capture thread on which it is caught like a block on a spring. What is the ratio of oscillation frequency for a fly with mass m to a fly with mass 2.5m?

A mass on a spring oscillates with a period of 2.2 s. (a) Where is the mass at t=8.3s if it starts from rest at x=5.0cm at t=0? (b) In what direction is the mass moving at t = 8.3 s? (c) What is the speed of the mass at t=8.3s?

A spring is compressed by 0.0610 m and is used to launch an object horizontally with a speed of 2.80 m/s. If the object were attached to the spring, at what angular frequency (in rad/s) would it oscillate?

A mass of 8.0 kg hangs from a spring attached to the ceiling. The spring has a spring constant of 500 N/m and it stretches 15.7 cm from its mean position. A student grabs the spring, applies a force and stretches it a further 6.7 cm downwards. The block is released and initially accelerates upward before undergoing simple harmonic motion. Calculate the initial vertical acceleration of the mass. (Units: m/s? , to 2 sig figs)

The springs of a 1600-kg car compress 4.70 mm when its 66.0-kg driver gets into the driver's seat. If the car goes over a bump, what will be the frequency of oscillations? Ignore damping. Express your answer using three significant figures. ΜΕ ΑΣΦ f= ? Hz

The position of an object in harmonic motion on the end of a spring is p=    2 cos(3t)- 4sin(3t),where is measured in seconds and is measured in inches. What is the velocity (in in/s) of the object at t= pi/3 seconds?
