An unstable particle with a mass equal to 3.34 ? 10-27 kg is initially at rest. The particle decays into two fragments that fly off with velocities of 0.971c and -0.851c, respectively. Find the masses of the fragments. (Hint: Conserve both mass-energy and momentum.)
m(0.971c) = kg
m(-0.851c) = kg
An aircraft, diving at an angle of 53with the vertical, releases a package at an altitude of 730 m. What is the speed of the aircraft
A pendulum is formed by pivoting a long thin rod about a point on the road. In a series of experiments, the period is measured as a function of the distance x among the pivot point and the rod's center.
A 1000kg car coasting at 72.0km/h on a level frictionless road comes to a 15 degree incline. Calculate how far the car will travel before coming to rest
A microscope uses an eyepiece with a focal length of 1.65 cm . Using a normal eye with a final image at infinity, What is the magnification of the microscope
A glider moves frictionlessly along an air track that has been tilted by 1.5 inches over a span of 1.00 meters. Illustrate what is the expected acceleration of the glider.
A car of mass 1,900 kg is initially traveling at a speed of 10 m/s. The driver then accelerates to a speed of 25 m/s over a distance of 500 m. Calculate the change in the kinetic energy of the car
A transformer is to be used to provide power for a computer disk drive that needs 5.0 V (rms) instead of the 120 V (rms) from the wall outlet. The number of turns in the primary is 415, and it delivers 500 mA (the secondary current) at an output v..
If the water in the river is flowing at 3.0 m/s, explain how long does it take the boat to make a round trip consisting of a 250 m displacement downstream followed by a 250 m displacement upstream?
Two blocks are moving along a horizontalfrictionless surface. The 4 kg block is moving to the right with aspeed of 6 m/s and the 2 kg block is moving to the left with aspeed of 3 m/s. How high upthe ramp does the combined object move
Compare this wavelength to the size of an atom (about 10^-10 m) by calculating the ratio: wavelength/(atom size).
