Question1
Car a is moving with a constant speed of 10m/s and passes car b which is at rest. Ten second later the latter follows with an acceleration of 0.5m/s^2. Establish the distance that the latter has to travel before it overtakes the former.
Question2
Red ribbon wound around a red spool (above) is taped to blue ribbon wound around a blue spool. The ribbon is essentially massless, but the solid cylindrical spools each have mass m and radius R. If the red spool can freely rotate on a set axle and the blue spool is positioned directly underneath with the ribbon taut, what is the downward acceleration of the blue spool? Gravity is downward.
Enter the reply in terms of some or all of the variables m, R and g.
A horizontal wire is free to slide on the vertical rails of a conducting frame, what is the terminal speed of the wire
In a diesel engine, the piston compresses air at 302 K to a volume that is 0.0623 of the original volume, What is the temperature of the air after the compression
Two points are located on a rigid wheel that is rotating with an increasing velocity about fixed axis. The axis is perpendicular to the wheel at its center. Point 1 is located on the rim and point 2 is halfway between rim and axis .at any given insta..
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,..
An electron passes through a point 3.75 cm from a long straight wire as it moves at 36.1% of the speed of light perpendicularly toward the wire. Find the magnitude of the electron\'s acceleration at that point
A village maintains a large tank with an open top, containing water for emergencies. The water can drain from the tank through a hose of diameter 6.60 cm. The hose ends with a nozzle of diameter 2.20 cm.
In order to drop a Pyrex glass marble 1.003 in diameter through the hole in the plate, how much must the temperature of the system be raised? (Assume the plate and the marble are always at the same temperature.)
An infinite line of positive charge lies along the y axis, with charge density ? = 2.80 ?C/m. Find the magnitude of the net force exerted on the dipole
One of the attempts to contain the spill involved pumping drilling mud into the well to balance the pressure of escaping oil against a column of fluid (drilling mud) having a density significantly higher than that of seawater and oil.
find the velocity and position of the particle asthe moment it reaches it's maximum x coordinate.
Two capacitors, C1 = 30 µF and C2 = 4.0 µF, are connected in parallel and charged with a 110 V power supply. Calculate the total energy stored in two capacitors
A small, 300 cart is moving at 1.90 on an air track when it collides with a larger, 1.00 cart at rest. After the collision, the small cart recoils at 0.890. Evaluate the speed of the large cart after the collision?
