Bob and Jane are flying in their airplane, headed eastward and accelerating uniformly. Directly above the relay tower near the airport it has a velocity of 25.9 m/s. They then fly a further distance of 43300 m and their air velocity is 45.5 m/s. Find the airplane's acceleration and calculate how much time elapses while it covers those 43300 m.
A ball is attached to the spring and allowed to come to rest. It is then pulled down 3.0 cm and released. If the ball makes 55 oscillations in 20 s, what are its mass and maximum speed
A moving electric charge is subject to a magnetic force in the presence of a magnetic field. Define how do you determine the direction of the magnetic force
High jumpers usually sustain fractures in the lower third of the fibula. The world record for the high jump is held by Javier Sotomayor (Cuba) at 2.45 m (1993). what is the stress in the fibula
The muon, with mass mμ=209me, acts as a heavy electron. The muon can bind to a proton to form a muonicatom. Calculate the ionization energy of this atom, and calculate the radius of the muonic atom in its ground state.
A ball moving at a speed of 3.0 m/s hits an identical stationary ball. what is the velocity and direction of the incoming ball after the collision
A proton moves at a speed of 1155 m/s in a direction perpendicular to amagnetic field with a magnitude of 0.74 T. What is the magnitude of the magnetic force on the proton?
A cosmic ray interacts for a mere 11fs with its detector. Having just learned about the uncertainty principle, Find the minimum uncertainty in that energy
A luminous object is 4.00m for a wall. You are to use a concave mirror to project an image of the object on the wall with the image 2.25 times the size of the object, how far should the mirror be from the wall
A 28 kg child plays on a swing having support ropes that are 1.80 m long. A friend pulls her back until the ropes are 43 from the vertical and releases her from rest.
a large cruise ship of mass 6.80 x 107 kg has a speed of 12.8 ms at some instant. a what is the ships kinetic energy at
The simple harmonic oscillator can be used as a model for the vibration of a diatomic molecule. Mass and Force Constant are on the order of 10^?26 kg and 10^3 N/m. This model will work if the temperature is sufficiently low (we assume it is in the gr..
A marble (radius 1.5 cm and mass 5.0 g) rolls without slipping down a ramp of vertical height 26 cm. What is the speed of the marble
