After driving a portion of the route, the taptap (2.94 * 10^4 N/m) is fully loaded with a total of 25 people with an average mass of 60 rm kg per person. In addition, there are three 15-rm kg goats, five 3-rm kg chickens, and a total of 25 rm kg of bananas on their way to the market. Assume that the springs have somehow not yet compressed to their maximum amount. How much are the springs compressed?
What is the speed of the large cart after the collision. A 345 g chunk of gold at 98.5 degrees Celsius is dropped into a 656 g of water at 22.5 degrees Celsius. What will final temperature of the gold be after the system reaches equilibrium.
The archerfish successfully shoots down the resting insect by spitting water drops at the same angle 60^circ above the surface and with the same initial speed v as before. At what height h above the surface was the insect.
A constant horizontal force Fa pushes a 1.50kg FedEx package across a frictionless floor on which a xy coordinate system has been drawn. gives package's x and y velocity components versus time t.
At a soft drink dispenser, a restaurant patron put 0.2 kg of crushed water ice, at a temperature of ?5 C, into an insulating cup. [In fact, the ice was slightly colder before it left the machine, but its warming to ?5 C cooled the inside surface o..
The cable pulls horizontally on the box, and a 50.30 bag of gravel rests on top of the box. The coefficients of friction between the box and roof are shown. The system is not moving. Find out the friction force on the bag of gravel.
What is the fractional change in the period of the pendulum.
A glucose-winged gull, ascending straight upward at 5.20 m/s drops a shell when it is 12.5 m above ground.
Through 5 successive 1.04 min intervals, a runner moves at the following constant speeds: 0.405 km/min, 0.220 km/min, 0.160 km/min, 0.163 km/min, and 0.323 km/min. compute the total distance travelled and average speed.
We have pumped 20 bbls of fluid from the cement unit. But we think that we should have already achieved 425 psi at the unit. We are rigged up to do F.I.T and have already pressure tested all surface lines and there are no leaks.
Calculate the kinetic energy acquired by a 11 kg nail when it is struck by the 530 kg hammer moving with an initial speed of 4.4m/s.
The light energy that falls on a square meter of ground over the course of a typical sunny day is about 20 MJ. The average rate of electric energy consumption in one house is 1.0 kW. Find the energy consumption and area required by the solar cell
A satellite with a mass of 750 kg is in orbit around the earth. It is initially located at the altitude (measured from the earth's surface) of 2.12 x 106 m. It is then moved into a new orbit, with an altitude of 4.25 x 10^6 m (again, measured from..
