A toy train is pushed forward and released at = 2.0 with a speed of 1.5 . It rolls at a steady speed for 2.8 , then one wheel begins to stick. The train comes to a stop 5.6 from the point at which it was released.What is the train's acceleration after its wheel begins to stick?
Determine out the work completed to move the particle from x = 0 to x_3 = 10.5 m graphically by determining the area under the F_x vs. x graph.
Water has a mass per mole of 18.0 g/mol, and each water molecule (H2O) has 10 electrons. (a) How many electrons are there in 9.42 liters of water? (1 liter is equivalent to 1.00 × 10-3 m3) (b) What is the net charge of all these electrons?
A light ray in the air is incident on the water 60^circ from the normal. Illustrate what is the ray's direction of travel in the glass?
what is the rms speed of the molecules. Graphically find out the distance and direction from Lake B to the base camp.
The average density of the planet uranus is 1.27 x 10^3 kg/m^3. The ratio of the mass of neptune to that of Uranus is 1.19. The ratio of the radius of Neptune to that of Uranus is 0.969. Find the average density of Neptune.
The volume control on a surround-sound amplifier is adjusted so the sound intensity level at the listening position increases from 21 to 59 dB. What is the ratio of the final sound intensity to the original sound intensity?
By how much does the potential energy of a 15.0-kg child increase. Find v0.
A 380-N, uniform, 1.50 m bar is suspended horizontally by two vertical cables at each end. A small object of weight 520 N is placed distance 0.5 m from the cable A. What is the tension in cable A.
A 54.00 kg pole vaulter running at 10 m/s vaults over the bar. Her speed while she is above the bar is 1.0 m/s. Avoid air resistance, in addition to any energy absorbed by the pole, and determine her altitude as she crosses the bar.
A uniform magnetic field of magnitude B= 1.2 teslas is directed toward the bottom of the page in the -y direction as shown above. At time t=0, a proton p in field is moving in the plane of the page with a speed v0= 4 x 10^7 meters per second in a ..
