A block is projected up a frictionless inclined plane with initial speed v1 = 3.54 m/s. The angle of incline is θ = 32.8 degree.
(a) Determine how far up the plane does it go?
m
(b) Determine how long does it take to get there?
s
(c) Find its speed when it gets back to the bottom?
m/s
A creamy salad dressing is made up of heavy cream, corn oil, If the cream layer is 2.20×10?2 m tall, the oil layer 2.80×10?2 m tall, and the vinegar layer 8.000e-3 m tall, what is the gauge pressure at the bottom of the jar
Your task is to design a boiler to produced saturated steam at 300 °C. Because energy costs money, you decide to use "waste" hot water streams already in the plant to feed the boiler. What is the steam velocity coming out of the boiler
an object of mass 1.60 kg is oscillating freely on a vertical spring with a period of 0.710 s. another object of
A 6220 kg space probe moving nose-first toward Jupiter at 140 m/s relative to the Sun fires its rocket engine, ejecting 80.0 kg of exhaust at a speed of 258 m/s relative to the space probe. What is the final velocity of the probe? m/s
a layer of water covers a slab of material X in a beaker. A ray of light traveling upwards follows the path indicated. Find the angle the light makes with the normal in the air
A raft is 3.9 m wide and 6.5 m long.When cargo is loaded onto the raft, it sinks 2.9 cm deeper into the water. What is the weight of the cargo
Nerve proagation in your body occurs when large electric fields in the cell membranes on neurons (1.0*10^7 N/C) cause ions to move through cell walls
The mass of the Space Shuttle orbiter is 8.8 x 104 kgand the period of its orbit is 82 minutes. Estimate thekinetic energy of the orbiter and the work done on it by gravitybetween the launch and orbit. (
In a 2-D coordinate system with axes the absolute temperature and volume, graph (a) an isobaric (constant pressure) change of one mole of an ideal gas for p=1 atmosphere, and (b) the same when p=2 atmospheres.
A car of mass 1110 kg travels at a speed of 20 ms-1 along a straight road. The driver sees a red traffic light ahead, and applies brakes. The coefficient of friction between the car tyres and the road is 0.83. Take the acceleration due to gravity to ..
A helicopter is flying in a straight line over a level field at a constant speed of 5.4 m/s, How would you calculate the angle the velocity vector makes with the ground at the instant before impact
