Q. A 246 kg wooden raft floats on a lake. When a 80 kg man stands on the raft, it sinks 4.0 cm deeper into the water. When he steps off, the raft vibrates for a while.
What is the frequency of the vibration?
What is the total energy of the vibration (ignoring damping)?
A radio controlled car increases its kinetic energy from 4J to 12J over the distance of 2 m. What was the average net force on the car during this interval.
For a spring-mass oscillator, if you triple the mass but keep the stiffness the same, what numerical factor does the period change? That is, if an original period was T and the new period is bT, what is b? It is useful to write out the expression ..
finding the thermal conductivity (k) of a box with total surface area of 1.20 m and a wall thickness of 4cm is made of an insulating material. a 10 W electric heater inside the box maintain the inside temp. at 15 C above the outside temp.
Two cars with equal mass collide head on. One car is going 18 mph. That car is push backward about 38 feet. What is the speed of other vehicle.
Starting from rest, you pull the string with a constant force F = 8 N along a nearly frictionless surface. At the instant while the center of the disk has moved a distance x = 0.12 m, a length d = 0.27 m of string has unwound off the disk.
so hydrogen atoms have a thermal velocity of about 1000 m/s. How does the energy stored in the magnetic field compare with the kinetic energy in a given volume of space.
An infinite non conducting sheet has a surface charge density σ = +5.80 pC/m2. (a) How much work is completed by electric field because of the sheet if a particle of charge q = +1.60 × 10-19 C is moved from the sheet to a point P at distance d = 3.56..
Write down an expression for the efficiency of the air cart bumper in terms of the initial and final kinetic energy of the cart. What defines a collision as elastic or inelastic.
A helicopter is ascending vertically with a speed of 9 m/s. At a height of 200 m above the Earth, a package is dropped from a window. How much time does it take for the package to reach ground.
A block of unknown mass, m, is brought into the configuration shown. It was measured that upon release the block shot upward a maximum distance of 2m. Calculate the mass of this block? The upper spring has a natural length of 1m, and the lower spr..
When two point charges are a distance R apart, their potential energy is -2.00 .How far (in terms of R) should they be from each other so that their potential energy is -6.00.
What are magnitude and direction of the force
