In mathematics, a ratio indicates how many times one number contains another. For example, if there are eight oranges and six lemons in a bowl of fruit, then the ratio of oranges to lemons is eight to six (that is, 8∶6, which is equivalent to the ratio 4∶3).

[someone help] The speed of the object 7 seconds after it is dropped is ___m/sec

nadezda [96]

9514 1404 393

Answer:

68.6 m/s

Step-by-step explanation:

The speed at a given time is the derivative of the height at that time.

dh/dt = -9.8t

At t=7, the speed is ...

-9.8(7) = -68.6 . . . . . meters per second (downward)

The speed is 68.6 meters per second.

_____

<em>Additional comment</em>

Height is considered to be positive in the up direction, so velocity and acceleration are also positive in the up direction. The derivative of height will be the velocity. Its negative sign in this case indicates the object is moving in the downward direction. The speed is the magnitude (absolute value) of the velocity.
