Q. Find the sum of these four vector forces: 14.0 N to the right at 35.0° above the horizontal, 31N to the left at 56° above the horizontal, 9.55 N to the left at 35.0° below the horizontal, and 24N to the right at 54° below the horizontal. (Hint: N stands for newton, SI unit of force. The component method allows the addition of any vectors - forces as well as displacements and velocities. Make a drawing of this situation, and choose the best axes for x and y so that you have the least number of components.)
Assume that a binary star system consists of two stars of equal mass. They are observed to be separated by 310 million kilometres and take 4.0 Earth years to orbit about the point midway between them.
An electron is shot upward directly perpendicular to the lower plate of a parallel plate capacitor. Its initial velocity is 3.0 x 104 m/s. What must be the potential of the upper plate if the electron stops just before reaching it? The lower plate..
A car makes a round trip for 100m in 10 seconds. What is the average velocity?
A cylinderical water tank of radius 10ft and height 30ft is half filled with water. How much work is essential to pump all of the water out through a hole in the top of tank.
Two children setup a "telephone" by placing a long, slender aluminium (Y = 6.9 × 1010 N/m2) bar that has a length of 6.1-m between their two houses. To communicate, the child taps a coded message on one end. How long do the sound waves take to reach ..
An automobile travels on a straight road for 40.0 km [E] at 30.0 (km/h). It then continues in the same direction for another 40.0 km [E] at 60 (km/h). Estimate the average speed, distance, displacement, & average velocity for the trip.
A person carries a long pole of mass 10kg and length 3.40 m at the angle of 60 degrees. Find the magnitude of the torque on the pole by reason of gravity.
A 1.35 block is attached to a spring with spring constant 14. While the block is sitting at rest, a student hits it with a hammer and almost instantaneously gives it a speed of 50. What are The block's speed at the point where = 0.750 A.
A meter stick supported at the 50 cm mark has masses of 300 g & 200 g hanging from it at the 10-cm & 60-cm mark, respectively. Where should we hang a third, 400-g mass to keep the meter stick balanced?
