Your taking a trip to a mysterious island where the temperature this time of year is usually about 230k. What is the temperature on the Fahrenheit scale.
One tire is inflated to a pressure of 40 and goes a distance of 18.0 ; the other is at 105 and goes a distance of 93.4. Assume that the net horizontal force is due to rolling friction only and take the free-fall acceleration to be = 9.80.
A ball rolls off a table with a horizontal velocity of 5 m/s If it takes 0.6 secs for it to reach the floor A. What is the verticle componet of the balls velocity just before it hits the floor? (use g= 10 m/s^2) B. What is the horizontal componet ..
You may also assume that v_0 gg sqrt{2gL}, so that the change in hammer's gravitational potential energy, as it drives the nail into the block, is insignificant.
A 0.15 kg ball is placed in a shallow wedge with an opening angle of 150.For each contact point between the wedge and ball, find out the force exerted on the ball. Assume the system is frictionless.
What mass can it support in water before sinking. Two concentric spherical shells with uniformly distributed masses M1 = kg and M2 = kg are situated as shown . Find out the magnitude Find the magnitude of the net gravitational force on a particle ..
iron atoms have been detected in the sun's outer atmosphere, some with many of their electrons stripped away. What is the net electric charge(in coulombs) of an iron atom with 26 protons and 7 electrons? Be sure to include the algebraic sign (+ or..
A metal slug is dropped from a height of 1/20 RM above the moon's surface. Find the speed with which the slug strikes the moon's surface
A 400kg piano slides 4.0 m down a 30 degree incline and is kept from accelerating by a man who is pushing back on it parallel to the incline. Find out the force exerted by the man.
Assuming that the pass was thrown at the optimal 45 ^circ angle, evaluate what was the speed at which the ball left the quarterback's hand?
Sea Launch mission planners are going to launch their Russian launch vehicle from a Lo = 3 degrees into LEO with an inclination of 34 degrees and the longitude of ascending node of 124 degrees. Current LST at the launch site is 1140.
The system is released from rest, and the string moves without slipping over pulley. If the larger mass is traveling at a velocity of 2.25 m/s when it has dropped 1m, how much mechanical energy was lost due to friction in the pulley's axle.
Various voltages V are applied across a resistor and for each value of V the current I through the resistor is measured, What is the resistance R of the resistor
