Consider a small frictionless puck perched at the top of a fixed sphere of radius R. If the puck is given a tiny nudge so that is begins to slide down
The length of a simple pendulum is 0.79 m and the mass of the particle (the "bob") at the end of the cable is 0.24 kg.
Ignore frictional losses and assume that the speed of the ball is 3.50 m/s at the bottom of the rise.
One particle has a mass of 3.00 10-3 kg and a charge of +7.60 µC. A second particle has a mass of 6.00 10-3 kg and the same charge.
Find an expression for v_0, the initial speed of the fired object. Express your answer in terms of some or all of the variables m, M, L, and theta.
After the collision, the electron is moving to the right at 0.6c and an outgoing photon moves to the left. What was the wavelength of the incoming photon?
A 2.0-kg solid cylinder of radius 0.5 m rotates at a rate of 40 rad/s about its cylindrical axis. What power is required to bring the cylinder to rest in 10 s?
A student performed an experiment to determine the density of neopentyl alcohol with the following results:
The axial magnetic field at a distance from a magnet falls-off as l/d3
"Machine epsilon" is a computer term describing the minimum quantity that can be added to 1 to give a different number
If A = (12i - 16j) and B = (-24i+10j), what is the magnitude of the vector C=(2A-B)?
In 1992, Akira Matsushima, from Japan, rode a unicycle across the United States, covering about 4800 km in six weeks.
A 200 g ball is thrown upwards with an initial kinetic energy of 10 Joules. What maximum height will the ball reach? (neglect air resistance).
What is the electric force (with direction) on an electron in a uniform electric field of strength 2780 N/C that points due east?
Use one of Fresnel’s equations to calculate the ratio of Et0, the amplitude of the transmitted electric field, to Ei0, the amplitude of the incident.
While exploring a cave a woman starts at the entrance and moves the following distances. She goes 75.0m north,250m east, 125m @an angle of 30 degrees
Determine the position of the center of mass of a solid triangular pyramid with vertices
A block of mass m slides down a frictionless incline. The block is released at height h above the bottom of the loop.
Two vectors having equal magnitudes (A) makes an angle z with each other. Find the magnitude and direction of the resultant
Assume the ropes and pulley have negligible mass and that friction can be ignored. (Use m1 for m1, m2 for m2, and h and g as necessary.)
A shopper pushing a cart through a store moves 30.0m south down onee aisle, then makes a 90 degree turn and moves 19.0m
What fraction of the initial kinetic energy is transferred to the target particle? At what angle does the target particle move after the collision?
A hiker walks due north for 4.0 km to reach point A and then northeast for 6.0 km to reach point B. Find by calculation or by scale drawing:
A projectile is fired straight up from the south pole of earth with an initial speed of 8.0km/s. Find the maximum height it reaches, neglecting effects.
Understanding physical principles is often very useful in everyday life. For example, a skater develops an intuitive understanding of angular momentum
