Part a is as follows: A long cylindrical insulator has a uniform charge density of 1.89 μC/m3 and a radius of 5 cm. What is the electric field inside the insulator at a distance of 4 cm?...

A hockey puck is hit on a frozen lake and starts moving with a speed of 12.0 m/s. Five seconds later it's speed is 6.00 m/s. What is the average value of the coefficient of kinetic friction between...

A dlock worker loading crates on a ship finds that a 20 kg crate, initially at rest on a horizontal surface requires a 75-N horizontal force to set it in motion. However, after the crate is...

On May 20, 1999, Robbie Knieval easily cleared a narrow part of the grand canyon during a world record setting long distance motorcycle jump 69.5m. He left the jump ramp at 10 degrees angle above...

An airplane lands on an aircraft carrier and is brought to the ships velocity of 10.3 m/s by an arresting cable in a distance of 114 meters. The mass of the air plane is 28,000 kg and it's velocity...

a golf ball is projected at a cliff of height h with an initial velocity of speed 50m/s at 60 the ball strikes point A on the cliff 6.5 seconds after it leaves the face of the club

An airplane is recovered aboard an aircraft carrier with a steel cable that brings airplane from 69 m/s to the ship speed of 15.0 m/s over displacement of 81 m determine the time, in seconds, that...

An airplane is recovered aboard an aircraft carrier with a steel cable that brings airplane from 69 m/s to the ship speed of 15.0 m/s over displacement of 81 m calculate the acceleration required...

In 1992, a 14-kg meteorite struck a car in Peekskill, NY, leaving a 20-cm deep dent in the trunk.    (a) If the meteorite was moving at 500 m/s before striking the car, what was...

Imagine that a sprinter accelerates from rest to a maximum speed of 10.8m/s in 1.8s. In what time interval will he finish the 100-m race if he keeps his speed constant at 10.8m/s for the last part...

The tests and scores that can help you gain admission to more selective colleges are changing. I see this as a tutor; though I am not an expert in educational statistics, I cobbled together some data that illustrates current trends. Starting in 1926, the SAT pioneered standardized college admissions tests. It provided valuable objective measures of academic potential. The SAT greatly... read more

A linear spring of spring constant K is used in a lab experiment. A block of mass m is attached to the spring and the resulting period T of the simple harmonic oscillations is measured. Blocks of...

An unstable particle produced in an accelerator experiment travels at constant velocity, covering 1.00 m in 3.58 ns in the lab frame before changing ("decaying") into other particles.
