Answer:

<u>According </u><u>to</u><u> the</u><u> </u><u>Given</u><u> Statement</u><u> </u>

Canon fires directly upwarda at 150m/s ( Initial speed, u )

Acceleration due to gravity is 10m/s²

Since Cannon ball reach it maximum height so its final velocity v will be 0 m/s .

Using Kinematic Equation

v = u + gt

On substituting the value we get

➥ 0 = 150 + 10 × t

➥ 150 = 10 × t

➥ 150/10 = t

➥ 15 s = t

So, it will take 15 seconds .

Answer:

maximum height reached: 15 s

Explanation:

using the formula: maximum height reached = [(sin(θ) * speed)/ gravity]

Here speed is 150m/s and gravity is 10 m/s² and as it does directly upwards, it has an angle of 90°

using the formula:

maximum height reached = [(sin(90) * 150)/ 10] = 15 s

To determine the height of a tall building such as Sears Tower in Chicago, Illinois a ball was dropped from the top of the build

Darya [45]

Answer:

The height of Sears Tower is 1448.5 feet.

Explanation:

<h3>We apply the free fall formula to the ball: </h3><h3> $y=v_{o} *t+\frac{1}{2} *g*t^{2}$ </h3><h3>y: The vertical distance the ball moves at time t </h3><h3> $v_{o}$ i: Initial speed </h3><h3>g=Gravity acceleration= $9.8*(\frac{\frac{1ft}{0.305m} }{s^{2} } )$ </h3>

Known information

We know that the vertical distance (y) that the ball moves in 9,5s is equal to height of Sears Tower (h).

Too we know that the ball is released from rest, then, $v_{0}$ =0

Height of Sears Tower calculation:

We replace in the equation 1 the data following;

$y=h$

$v_{o} =0$

$g=32,1\frac{ft}{s^{2} }$

$t= 9,5s$

$h=0*9.5+\frac{1}{2} *32.1*9.5^{2}$

$h=1448.5 ft$

Answer: The height of Sears Tower is 1448.5 ft

How is the independent variable affected by the dependent variable

stiv31 [10]

Answer:

A dependent variable is a variable that is tested in an experiment. An independent variable is that can be modified. Depending on what you are testing, the dependent variable will change accordingly to the dependent variable.

Kate is riding on a train and notices that the wildflowers by the side of the tracks seem to be moving by much faster than the m

madreJ [45]

Answer: motion parallax

Explanation:

Motion parallax refers to a form of depth perception whereby objects that are closer to an individual appears to move at a faster speed than the objects that are far.

Therefore, Kate is riding on a train and notices that the wildflowers by the side of the tracks seem to be moving by much faster than the mountains in the distance is an example of motion parallax.
