Q. A guitar string is vibrating in its fundamental mode, with nodes at each end. The length of the segment of the string that is free to vibrate is 0.380 m. The maximum transverse acceleration of a point at the middle of the segment is 8800 m/s^2 and the maximum transverse velocity is 3.50m/s.
1). What is the amplitude of this standing wave?
2). what is the wave speed for the transverse travelling waves on this string?
A 0.27 kg rock is thrown perpendicularly upward from the top of the cliff that is 32 m high. When it hits the ground at the base of cliff, the rock has a speed of 29 m/s. suppose that air resistance can be ignored, find out A) initial speed of the ro..
An object has a kinetic energy of 317 J and the momentum of magnitude 24.0 kg · m/s.
An engine does 20000 J of work and rejects 6120 J of heat into a cold reservoir whose temperature is 285 K. What would be the smallest possible temperature of the hot reservoir.
Two boxes, m1 = 1.0 kg with a coefficient of kinetic friction of 0.10, and m2 = 2.0kg with a coefficient of 0.20, are placed on a plane inclined at 0 = 30o.
A 0.105-kg ball is dropped from rest. If magnitude of the ball's momentum is 0.790 kg · m/s just before it lands on the ground, from what height was it dropped.
Runner A is at first 5.4 km west of a flagpole and is running with a constant velocity of 2.6 km/h due east. Runner B is initially 3.0 km east of the flagpole and is running with the constant velocity of 8.8 km/h due west. What would be the distance ..
What intensity level of the horn's sound is observed by somebody waiting at an intersection 58m from the train.
Suppose you see two main-sequence stars of the same spectral type. Star 1 is dimmer in apparent brightness than Star 2 by a factor of 100. What can you conclude? (Overlook any effects that might be caused by interstellar dust and gas.)
If the two balls started rolling at the same time at a point 1.2 m behind the edge of the table, will they reach the floor at the same time? define.
How does this number of calories compare with the number of calories required to vary the same gram of 100 degree C boiling water to 100 degree C steam.
An object of mass m is attached to a horizontal spring, stretched to a displacement A from equilibrium and released, undergoing harmonic oscillations on a frictionless surface with period T0. The experiment is then repeated with a mass of 4m. The sub..
A small piece of dust of mass m = 1.50g travels horizontally through an electric air cleaner in which the electric field is 498N/C. The electric force on the particle is equal to weight of the particle.
