Q. A 15m uniform ladder weighing 500 N rests against a frictionless wall. The ladder makes 60 angles with the horizontal.
1) find the horizontal and vertical forces that ground exert on the base of the ladder when an 800N firefighter is 4.00m from the bottom
2) if the ladder is just on the verge of slipping when the firefighter is 9.00m up, what coefficient of static friction between the ladder and the ground.
Once the station is completed, it is set rotating at a rate that requires an object at the rim to have radial acceleration, thereby simulating Earth's surface gravity. This is accomplished using two small rockets, each with 130 thrust that are mounte..
A proton starting from rest is accelerated in a cyclotron to a speed of 3.0•106 m/s. Find the work done on a proton by the electrical force of the cyclotron.
A 3.4 k and a 2.4 k resistor are connected in parallel; this combination is connected in series with a 1.8 k resistor. If each resistor is rated at 1/2 W (maximum without overheating), what is the least voltage that can be applied across the whole..
A 16 kg steel ball is launched from a cannon at an angle of 20 degrees above the horizontal. The cannon exerted an average force of 1200 Newtons on the ball during launch. Now that ball is in the air and has almost reached its target, what is the ..
Two water reservoirs are open to the atmosphere. The manometer contains mercury with the density of 13,600kg/m cubed. What is the difference in elevation if the manometer reading is 25cm.
Decide the speed with the rock is thrown
An airplane is flying with a velocity of 95m/s at an angle of 19.0^circ above the horizontal. When the plane is a distance 124m straight above a dog that is standing on level ground, suitcase drops out of luggage compartment.
A metal block of mass m slides on a horizontal surface that has been lubricated with a heavy oil so that the block suffers a viscous resistance that varies as the 3/2 power of the speed F(v)=-cv^3/2. If the initial speed of the block is v0 at x=0,..
Six mass pieces of 100g each are placed on a mass holder of 140g which is hung from a string. Analyse the tension in the string.
A diving board of length 3.00m is supported at a point 1m from the end, and a diver weighing 520 m stands at the free end . The diving board is of uniform cross section and weighs 270m.
A 21 kg sled is being pulled across a horizontal surface at a constant velocity. The pulling force has a magnitude of 80.5 N and is directed at an angle of 30° above the horizontal. Determine the coefficient of kinetic friction.
