What is the object's displacement from 15 s to 40 s? What is the object's velocity from 15 s to 40 s? Is it positive or negative? At what point is the object's speed the fastest? Acceleration is the rate of change of velocity. It occurs when an object speeds up, slows down, or changes direction. Has direction. a = (Vf…
A bat chirps to locate a tasty lunch. The chirp travels at the speed of sound in air and its echo is heard 1 s after the chirp. The distance to the lunch is ______ meters
1) You stand at the edge of the Grand Canyon and shout out, “Eureka!" 6.57 seconds later, you hear your own echo off the far canyon wall. How far is it to the opposite wall if sound travels at 345 m/s?
(a) A soccer player kicks a rock horizontally off a 39 m high cliff into a pool of water. If the player hears the sound of the splash 3.02 s later, what was the initial speed given to the rock (in m/s)? Assume the speed of sound in air is 343 m/s. m/s (b) What If? If the temperature near the cliff suddenly falls to 0°C, reducing the speed of sound to 331 m/s, what would the initial speed of the rock have to be (in m/s) for the soccer player to hear the sound of the splash 3.02 s after kicking the rock? m/s
In camping, you drop a stone from a 1st spot to lake. The splash is heard 4 seconds later. After walking for a while, you drop a stone again at a 2nd spot to the same lake. This time the splash is heard 12 seconds later. The height of the 2nd spot is ___ times the 1st spot.
-L.1971+38.67 Time (in seconds) The driver of a vehicle applies the brakes, softly at first, then harder, coming to a complete stop after 7 sec. The velocity as a function of time is modeled by the function v(t) = -1.197t² + 58.67,. where v is in feet per second, t is in seconds and 0sis 7. How far did the vehicle travel while the driver was braking? Velocity (in feet per second)
The earth's crust is broken up into a series of more-or-less rigid plates that slide around due to motion of material in the mantle below. Although the speeds of these plates vary somewhat, they are typically about 5.2 cm/ycm/y. Assume that this rate remains constant over time. a) If you and your neighbor live on opposite sides of a plate boundary at which one plate is moving northward at 5.2 cm/ycm/y with respect to the other plate, how far apart do your houses move in a century? Express your answer in meters b) Los Angeles is presently 550 kmkm south of San Francisco, but is on a plate moving northward relative to San Francisco. If the 5.2 cm/ycm/y velocity continues, how many years will it take before Los Angeles has moved up to San Francisco? Express your answer in years.
