A suspension bridge is 62.0 m above the level base of a gorge. A stone is thrown or dropped from the bridge. At the location of the bridge, g has been measured to be 9.83 m/s2. In each of the following, assume that there is no air resistance. (a) If you drop the stone, how long does it take for it to fall to the base of the gorge? s (b) If you throw the stone straight down with a...

1. A bullet is fired at the center of a target that is 103 meters away. If the bullet has an initial velocity of 810 m/s, how far below the center of the target will the bullet be when it hits the target? Take gravitational acceleration to be 10 m/s2. (Hint: How long will it take for the bullet to reach the target?) 2. A ball rolls off a table with a horizontal velocity of 8 m/s. If the table is...

19. One car is traveling at 14 m/s, another car 28 m/s. Both have brakes that provide -3.50 m/s2 acceleration. What are the stopping times and stopping distances for both cars? 20. A fully loaded 737 aircraft takes off at 75 m/s. If its acceleration is a constant 3.0 m/s2, how long must the runway be? How much time does it take the 737 to reach takeoff?
