Q. There is a beam that weighs 1500 kilograms and is twenty meters in length. It has a 15000 kilogram mass on the right side, five meters from the center of gravity. Please calculate the net tension of each brace that is holding up the beam on both sides.
Q. Two forces, 397N at 11 degrees and 334N at 30 degrees are applied to a car in an effort to accelerate it. What is the magnitude of the resultant of these 2 factors? Units in N
A 2.16 kg block on a horizontal floor is attached to a horizontal spring that is initially compressed 0.0320 m. The spring has force constant 840 N/m.
Two students are on a balcony 18.30 m above the street. One student throws a ball, b1, vertically downward at 16.80 m/s. At the same instant, the other student throws a ball, b2, vertically upward at the same speed.
What is the velocity of observer B relative to observer A . A diver shines a light up to surface of a flat glass-bottomed boat at an angle of 36 relative to the normal.
What is the instantaneous power, at a time of 0.00700 seconds, dissipated by a 200 ohm resistor in a resonant AC circuit powered by a generator with a 21.0 V highest potential difference operating at 5000 rad/s .

Suppose the gravitational force between two massive spheres is 100 N. If the distance between the spheres is doubled, what is the force between the masses.
Two objects are maintained at constant temperatures, one hot and one cold. Two identical bars can be attached end to end, as in part a of drawing, or one on top of the other, as in part b. When either of these arrangements is placed between the hot a..
