A 0.400-kg object attached to a spring with a force constant of 8.00 N/m vibrates in simple harmonic motion with an amplitude of 12.2 cm. The maximum speed is 54.6 cm/s. CALCULATE THE MAXIMUM VALUE OF ITS ACCELERATION
A 1.50-kg object attached to a spring moves without friction (b = 0) and is driven by an external force given by the expression F = 5.60sin(2?t), where F is in newtons and t is in seconds. The force constant of the spring is 29.0 N/m. The resonance angular frequency of the system is 4.4 s^-1. The angular frequency of the driven system is 6.28 s^-1. FIND THE AMPLITUDE OF THE MOTION.
As a positron moves through a region of space, its speed increases from 2.80 X10^6 m/s to 8.00 X10^6 m/s. The electric force is the only force acting on the positron. Across what potential difference did the positron travel?
A young boy swings a yo-yo horizontally above his head at an angular acceleration of 0.32 rad/s^2. If the tangential acceleration of the yo-yo at the end of the string is 0.15 m/s^2, how long is string.
A 5 kg mass attached to a horizontal spring is pulled from its equilibrium position by 3 m and let go. what is the maximum velocity of the mass
There are many estimates of the number of stars in the universe. One estimate is that there are 1010 stars in the Milky Way galaxy, and that there are 1010 galaxies in the universe.
Tension is maintained in a string. The observed wave speed is 25 m/s when the suspended mass is 3.0 kg. (a) What is the mass per unit length of the string?
what is the depth d. what is the angle of refraction.
A 2.0 kg mass (mA) and a 5.50 kg mass (mB) are connected to a lightweight cord that passes over a frictionless pulley. The pulley only changes the direction of the force exerted by the rope.
Does an apple tree exert a gravitational force on the earth and if so, how large of a force? Consider and explain this question when the apple is attached to the tree, and when it is falling.
Give the force exerted on the bag, to validate your reply.
A block resting on a smooth surface explodes into three pieces. A 465 gram piece travels at 1.7 m/s, a 1999 gram piece travels 0.7 m/s, calculate the mass and direction of the third piece.
On a hot summer afternoon, Keith is out fishing in a rowboat when he decides to jump into the water and go for a swim, what is its velocity in the opposite direction after he jumps
Stone with a mass of 0.800 {rm kg} is attached to one end of a string 0.900 {rm m} long. The string will break if its tension exceeds 65.0 {rm N}. The stone is whirled in a horizontal circle on a frictionless tabletop; the other end of the string rem..
