Chapter 6. Uniform Acceleration Problems: Speed and Velocity 6-1. A car travels a distance of 86 km at an average speed of 8 m/s. How many hours were required for the trip? [pic] [pic] t = 2.99 h 6-2. Sound travels at an average speed of 340 m/s. Lightning from a distant thundercloud is seen almost immediately. If the sound of thunder reaches the ear 3 s later‚ how far away is the storm? [pic] t = 58.8 ms 6-3. A small rocket leaves its pad and travels a

HOMEWORK PROBLEMS Chapter-4: MOTION IN TWO DIMENSIONS 1 A particle starts from the origin at t = 0 with a velocity of 6.0[pic] m/s and moves in the xy plane with a constant acceleration of (-2.0[pic] + 4.0[pic]) m/s2. At the instant the particle achieves its maximum positive x coordinate‚ how far is it from the origin? [pic] 2 At t = 0‚ a particle leaves the origin with a velocity of 5.0 m/s in the positive y direction. Its acceleration is given by [pic] = (3.0[pic] - 2.0[pic]) m/s2. At the

Task-1(P1) a. ‘For every action there is an equal and opposite reaction’ When a balloon is inflated plus released with no tying the inlet‚ the balloon flies all above the place as the air is released. The balloon and the air flowing out of the balloon travel in opposite directions. The Third Law of Motion states that every action has an equal and opposite reaction. This information can be used to create a balloon pinwheel. Tape the inlet of the balloon around the straw at the end opposite the

required velocity in the ’Velocity demand’ vector and to subtract the actual velocity‚ found by the body sensor‚ to give an acceleration until the required velocity is achieved. By increasing the gain there is an overall decrease in the velocity and with an extreme increase in gain there is a decreases to values below the initially x-velocity. This analysis also corresponds to an extreme decrease in gain whereby the velocity therefore increases dramatically to very high values of velocity. By imposing
