Q. A jetliner is moving at a speed of 235 m/s. The vertical component of the plane's velocity is 42.9 m/s. Determine the magnitude of the horizontal component of the plane's velocity.
A grating has 776 lines per centimeter. Find out the angles of the first three principal maxima above the central fringe when this grating is illuminated with 603 nm light.
A car traveling at a constant speed of 22.5 m/s passes a trooper hidden behind a billboard. One second after the speeding car passes the billboard, the trooper sets off in chase with a constant acceleration of 3.90 m/s2.
A electron is accelerated from rest by the potential difference of 350 V. It then enters a uniform magnetic field of magnitude 200 mT with its velocity perpendicular to the field.
A high diver of mass 65kg jumps off a board 10m above the water. If her downward motion is stopped 1.70 s after she enters the water, what average force did the water exert on her.
A 2.3 box, starting from rest, is pushed up a ramp by a 10 force parallel to the ramp. The ramp is 2.0long and tilted at 17 . The speed of the box at the top of the ramp is 0.80 .
A vessel whose walls are thermally insulated contains 2.00 of water and 0.550 of ice, all at a temperature of 0.0. The outlet of a tube leading from a boiler in which water is boiling at atmospheric pressure is inserted into the water.
Before starting this problem, review Conceptual. The force vector A has the magnitude of 75.0 newtons (N) and points due east. The force vector B has a magnitude of 101 N and points 72.9 ° north of east.
The loaded cab of an elevator has a mass of 3.6 x 10^3 kg and moves 193m up the shaft in 20s at constant speed. At what average rate does the force from the cable do work on the cab.
What is the acceleration in m/s of a 0.001kg bullet if the force of recoil gives an acceleration of 4.390 m/s? The gun has mass of 0.20 kg.
The cubit is an ancient unit. Its length equals six palms. (A palm varies from 2.50 to 3.50 inches depending on the individual.) We are told Noah's ark was 300 cubits long, 50 cubits wide and 30 cubits high.
If the particle is released from rest at the midpoint C, s=100mm, and the acceleration is measured as a= (4s) m/s2 , where s is in meters, evaluate the velocity of the particle when it reaches plate B, s=200mm, and the time it needs to travel C to ..
