The catapult on an aircraft carrier can take an aircraft from 0 to 209 mph (the launch speed) in 9 seconds, at which time the aircraft launches.Express the launch speed in SI units (meter-kilogram-second system - not km/hr).
A 61.2-kg boy at rest on roller skates throws a 0.915-kg ball horizontally with a speed of 7.44 m/s. With what speed does the boy recoil
A projectile is fired at time t = 0.0 s, from point 0 at edge of a cliff, with initial velocity components of vix=30m/s and viy = 100m/s. The projectile rises, and then falls into the sea at point P. The time of flight of the projectile is 20s.
The aurora is caused when electrons and protons, moving in the earth's magnetic field of ?5×10?5 T, collide with molecules of the atmosphere, find Radius of the electron and proton in m
A spelunker is surveying a cave. She follows a passage that takes her a distance 189 straight west, then a distance 220 in a direction 45 east of south, after that a distance 280 at 30 east of north. After a fourth unmeasured displacement she find..
A boy whirls a stone using an r-m long string in a horizontal circle h m above the ground. The string broke, and the stone flies off horizontally and strike the ground x m away.The velocity with which the stone flies off the circle is? The centrip..
A soccer player 'heads' the size 5 ball deflecting it by 46.0°, and keeps its speed of 15.90 m/s constant. A size 5 ball has a mass of approximately 0.421 kg. What is the magnitude of the impulse which the player must impart to the ball.
What are the original charges on each sphere
Find out the average speed for the trip
A stream of protons and electrons are shot horizontally (from the left edge of the page to the right) with a speed of 1.2 x 10^6 m/s, What is the radius of the curvature and the direction for the curvature that each of these particles undergoes
A person exerts a horizontal force of F = 169N in the test apparatus. (h = 0.32m.) Find the horizontal force M that his flexor muscle exerts on his fore arm.
One way to measure on another planet or moon by remote sensing is to measure how long it takes an object to fall a given distance. A lander vehicle on a distant planet records the fact that it takes 3.17 for a ball to fall freely 11.26.
A irregular piece of metal has a dry mass of 5.7 kg. Once it is submerged it has an apparent mass of 2.4 kg. What is the density of the piece of metal
