Q. A vertical spring with a spring steady of 420-N/m is mounted on the floor. From directly above the spring, which is unstrained, a 0.30 kg block is dropped from rest. It collides with and sticks to the spring that is compressed by 2.5-cm in bringing the block to a momentary halt. Assuming air resistance is negligible; from what height (in cm) above compressed spring was the block dropped?
Identical samples containing 32P are measured for a period of 1 hr in a counter having an efficiency of 44 percent and a negligible background. From a large number of observations, the mean number of counts in 1 hr is (2.93 x 10^4)
A 3000 pound car crashes into a concrete jersey barrier moving 3 sections (totaling 12,000 pounds) laterally 24 inches. How fast was the car going on impact.
Establish the average net force
A ball falls straight down onto a wedge that is sitting on frictionless ice. The ball has a mass of 3.11kg, and the wedge has a mass of 5.39 kg. The ball is moving the speed of v = 4.45m/s when it strikes the wedge, which is initially at rest.
What are magnitude and direction of net electrostatic force
The rms speed of the molecules in 1.8 of hydrogen gas is 1600 m/s. What is total translational kinetic energy of the gas molecules.
A meteoroid is speeding through the atmosphere, traveling east at 21.5 km/s while descending at 19.0 km/s. What is its speed, in km/s.
A 27 pound meteorite struck a car, leaving a dent 26cm deep in the trunk. If the meteorite struck the car with a speed of 620m/s, what was the magnitude of its deceleration, assuming it to be constant.
What is the magnitude
calculate the speed of the block at the instant the dielectric leaves the capacitor assuming it starts at rest and that the voltage across the capacitor after the dielectric is removed is measured to be 900 V.
find out kinetic energy of ball at the highest point of motion.
