A ball is tossed into the air from height of 8 feet with an initial velocity of 8 feet per second. find the time r(in seconds) i

t takes for the object to reach the ground by solving the equation -16t + 8t + 8 = 0 you trimmed a large strip of wallpaper from a scrap to fit into the corner of a wall you are wallpapering. you trimmed 15 inches from the length

For this case we have the following equation:
 -16t + 8t + 8 = 0
 The first thing we must do is rewrite the equation correctly.
 We have then:
 -16t ^ 2 + 8t + 8 = 0
 Solving the polynomial we have:
 t1 = -1/2
 t2 = 1
 We discard the negative root because we want to find the time.
 Answer:
 it takes for the object to reach the ground about:
 t = 1 second

Answer:

Yes

Explanation:

Yes, this is a random error generating because of statistical constraint. We only have finite number of data points. As per this, if we plot our observation we will get a gaussian (inverse bell ) shaped curve with mean equal to central value.

During a particular time interval, the displacement of an object is equal to zero. Must the distance traveled by this object als
Gnom [1K]

Answer: No, we can have a displacement equal to 0 while the distance traveled is different than zero.

Explanation:

Ok, let's write the definitions:

Displacement: The displacement is equal to the difference between the final position and the initial position.

Distance traveled: Total distance that you moved.

So, for example, if at t = 0s, you are in your house, then you go to the store, and then you return to your house, we have:

The displacement is equal to zero, because the initial position is your house and the final position is also your house, so the displacement is zero.

But the distance traveled is not zero, because you went from you traveled the distance from your house to the store two times.

So no, we can have a displacement equal to zero, but a distance traveled different than zero.
