Instead of handing out candy like a well-adjusted person on Halloween, grumpy, anti-social Professor Sosa decides to stand on to

Likurg_2 [28]

Answer: The bag of candy corn will take 5 seconds to land on the floor and it will hit it with velocity of 49m/s.

Step-by-step explanation: A free falling object has only Gravitational Force acting on it, so acceleration will be due to gravity, which has magnitude

g = 9.8m/s².

As Professor Sosa drops the bag, its initial velocity and time are 0.

The building has a height of 400ft, so adjusting units: y = 121.92 m and $y_{0}$ = 0.

For this problem, going down will be the positive reference.

Then:

$y=y_{0}+v_{0}t+\frac{g}{2}t^{2}$

$\Delta y=v_{0}t+\frac{g}{2}t^{2}$

$121.92=\frac{9.8}{2}t^{2}$

$t=\sqrt{\frac{121.92*2}{9.8} }$

t ≈ 5

It will take 5s for the candy corn bag to land on the ground.

Acceleration is the change in velocity per change in time, so:

$g=\frac{\Delta v}{\Delta t}$

As initial velocity and time are 0 and rearraging it:

v = g.t

v = 9.8*5

v = 49

The bag will hit the ground with velocity of magnitude 49 m/s.

Can someone help me with this?

Nimfa-mama [501]

Answer:

Kite x=1, y=7

Step-by-step explanation:

It is a kite.

The two lines on the bottom corners of the kite mean they have the same value.

X=1 so 3x+4

3 *1 +4=7

And: x+6

1+6=7.

X+4=1+4=5.

Y=7 so y-2

7-2=5.

Bill was looking at 13 different colors to paint his bedroom. He liked about three fourths

d1i1m1o1n [39]

Answer:

As a fraction: 39/4 or 9 3/4

As a decimal: 9.75

As a percentage: uhhhhh- 75% of the colors.

As an integer: 10

Step-by-step explanation:

Multiplying fractions, you get 39/4 or 9 3/14

Pull out your calculator(or divide on paper), to get 9.75

Round that to 10.

3/4 = 75%

Hope this helps!

Answer:

this is basic algebra. For the first question (if you add five to one side what must also happen), the answer is that you must add 5 to the other side. use this to answer the other ones.
