On a force table, you add weights to the weight hangers until the ring does not touch the centering pin and is in the exact center of the table. You can also reposition the pulleys a bit. The greatest source of error is friction. To minimize this lift the ring slightly and release it. What type of friction are you minimizing?
A river flows due east at 1.50 m/s. A boat crosses the river from the south shore to the north shore by maintaining a constant velocity of 15 m/s due north relative to water.
After a day of testing race cars, you decide to take your own 1420 kg car onto the test track. While moving down the track at 10 m/s, you regularly accelerate to 32m/s in 10 s. What is the average net force that you have applied to car during the ..
A 6.0 kg sled is initially at rest on horizontal road. The coefficient of kinetic friction between the sled and the road is 0.40. The sled is pulled a distance of 3.0 m by a force of 37 N applied to the sled atan angle of 30° to the horizontal.
