Two teams of nine members each engage in a tug of war. The first team's members have average masses of 70 kg and exert average forces of 1350 N horizontally. The second team's members have average masses of 75 kg and exert average forces of 1375 N horizontally.
(a) What is the acceleration of the two teams?
m/s2
(b) What is the tension in the section of rope between the teams?
N
A uniform plank of length 5.8 m and weight 202 N rests horizontally on two supports, with 1.1 m of the plank hanging over the right support (see the Illustrataing). To what distance x can a person who weighs 441 N walk on the overhanging part of t..
What is the net charge inside the sphere.
A transverse electromagnetic plane wave with a frequency of 2.84 MHz travels directly away from you (- z direction). At time t = 0, your magnetic field detector measures a magnetic field of 4.57 × 10-8 Tesla pointing down (- y direction) that further..
The block is acted upon by its weight w=200lb, a horizontal force Q=600 lb and pressure P exerted by the inclined plane. The resultant R of these forces is up and parallel to the incline there by sliding the block up it. Establish P and R.
The block is spun at 60 rpm, then the temperature of the rod is slowly increased. When the wax melts, the block slides out to the end of the rod. Determine the final angular velocity? Give your answer in rpm.
The coefficient of kinetic friction is 0.400. Illustrate what should be the magnitude of P, so that the net work done by it and the kinetic frictional force is zero?
A uniform magnetic field of magnitude B = 0.020 T is in the positive y-direction. Determine the magnitude and direction of the magnetic force on each segment.
A golfer drives a 0.046kg golf ball from an elevated tee, giving the ball an initial horizontal velocity of 45 m/s. (a) what is the magnitude of the average force exerted by the club on the ball if the contact time for the golf club on the ball du..
A 4.22 box sits at rest at the bottom of a ramp that is 7.74 long and that is inclined at 40.0 above the horizontal. The coefficient of kinetic friction is 0.40, and the coefficient of static friction is 0.50.
A farsighted person has a near point of 50-cm from her eyes. She wants glasses that would let her see objects at a distance of only 25.00 cm from her eyes. Determine out the focal length of the glasses needed if the glasses are 2 cm and 3 cm from ..
If the coefficient of kinetic friction between the box and the roof is 0.55, with what speed must you push the box to have it gently come to rest right at the edge of the roof.
A beam of unpolarized light of intensity 12.o w/m^2 is incident on an ideal linear polarizer, P1, whose transmission axis is in the vertical (y) direction, What is the intensity of light emerging from P1
