A towed caravan, of mass 600 kg is attached by a ball hitch to a car. They are driven round a corner of 35 m radius. The coefficient of friction is 0.5 between caravan wheels and wet road. The centre of gravity of the caravan is 1.2 m above the road. Half the track (distance laterally between wheels) is 0.85 m. Calculate the maximum speed in m/s that the caravan can go round the corner without overturning or sliding.
It compresses the spring, and then is pushed back in the opposite direction by the spring, eventually losing contact with the spring.
two grounded conducting plans meet at an angle 90 degrees at the origin. a point charge q is a distance r0 from the
the snow exerts a retarding force on the sled that points opposite to the direction of motion, and has a magnitude of 57. Find out the acceleration of the sled and child.
in a certain right triangle the two sides that are perpendicular to each other are 3.70 m and 5.40 m long. what is the
During a thunderstorm the electric field at a certain point in the earth's atmosphere is 1.11 105 N/C, directed upward, Find the acceleration of a small piece of ice of mass1.08 10-4 g
One common kind of computer keyboard is based on the idea of capacitance. Each key is mounted on one end of a plunger, find the change in capacitance that is detected by the computer
A point charge q1 = -4.00 nC is at the point x = 0.60 m, y = 0.80 m, and a second point charge q2 = +6.00 nC is at the point x = 0.60 m, y = 0. Compute the magnitude of the net electric field at the origin due to these two point charges.
A block with mass m =6.4 kg is hung from a vertical spring. When the mass hangs in equilibrium, the spring stretches x = 0.27 m. what is the magnitude of the net force on the block
A uniform magnetic field of 25 mT magnitude points into the page. The wire is 1.4m long and straight, but has a loop smack in the middle. The loop has a radius of 3cm. The wire is then quickly - within 50ms - pulled taut and the loop disappears. Calc..
A parallel-plate capacitor is constructed using a dielectric material whose dielectric constant is 2.00 and whose dielectric strength is 1.00 108 V/m. Find the minimum area of the capacitor plates
what are the wavelengths of electro magnetic waves in free space that have frequencies of a) 5.00 x 10^19Hz, b) 4.00 x 19^9.
Red light (n=1.520) and violet light (n=1.538) traveling in air are incident on a slab of crown glass. Both colors enter the glass at the similar angle of refraction. The red light has an angle of incidence of 30.00 degrees. What is the angle of occu..
