A small, 300 g cart is moving at 1.10 m/s on an air track when it collides with a larger, 4.00 kg cart at rest. After the collision, the small cart recoils at 0.890 m/s. What is the speed of the large cart after the collision (answer in m/s please)?
solenoid is formed by winding 23.0 m of insulated silver (resistivity 1.59 x 10-8 Ω·m) wire around a hollow cylinder. The turns are wound as closely as possible without overlapping, and insulating coat on the wire is negligibly thin.
For a common emitter amplifer, current gain is 70. If the emitter current is 8.8mA, Calculate the collector and base current. Also calculate current gain
You hang the rod vertically and attach a 74 kg mass to the bottom, and you observe that the bar becomes 1.74 cm longer. From these measurements, it is possible to conclude the stiffness of one interatomic bond in titanium.
Find the equation for the acceleration of the moving body at any time.
An 8g bullet is fired at a speed of 216 m/s into a 190 g block that is initially at rest at the edge of a table of 1m height. The bullet fully embeds itself in the block before the bullet-block system launches off the table. How far in the x-direc..
A boat moves relative to water with a velocity which is n =2 times less than the river flow velocity. At what angle to the stream direction should the boat move to minimize drifting.
An electron is accelerated by a constant electric field of magnitude 290 N/C. (a) Find the acceleration of the electron.
The diagram on the left below shows two resistors in series with an ideal battery, in the diagram on the right; a third resistor has been added in parallel with R2. Calculating the resistance, current and potential difference.
A horizontal uniform bar of mass 2.7 and length 3.1 is hung horizontally on two vertical strings. String 1 is attached to the end of bar, and string 2 is attached a distance 0.7 from other end. A monkey of mass 1.6 walks from one end of the bar to th..
A parallel-plate capacitor has a capacitance of c1 = 5.5 ?F when filled with air and c2 = 33 ?F when filled with a dielectric oil at potential difference of 12 V, Input an expression for the permittivity of the oil
How far above the base of the cliff does this happen. What is an acceleration at the point where the block begins to slip.
Suppose that you hear a clap of thunder 18.4 s after seeing the associated lightning stroke. The speed of sound waves in air is 343 m/s and the speed of light in air is 3.00 x10^8 m/s. How long are you from the lightning stroke.
