Answer:

3.19 seconds

Step-by-step explanation:

Given:

Phone gets dropped from a Height = 150 ft

To find:

Time taken for the phone to reach the ground = ?

Solution:

First of all, let us learn about the formula of distance in terms of Initial speed u; Time t and Acceleration a:

$s=ut+\dfrac{1}{2}at^2$

Here the phone is dropped from a height so a = g m/ $s^2$ i.e. acceleration due to gravity.

g = 9.8 m/ $s^2$

s = 150 ft

Initial velocity, u = 0

Putting all the values in the formula:

$150=0 t+\dfrac{1}{2}gt^2\\\Rightarrow 50=\dfrac{1}{2}\times 9.8 \times t^2\\\Rightarrow t^2=\dfrac{50}{4.9 }\\\Rightarrow t^2=10.20\\\Rightarrow t = 3.19\ sec$

So, the time taken is 3.19 seconds.

I wished I’d bought the game last week for $199.00. I missed the sale, and now it’s an additional 25%. What will it cost me now

kumpel [21]

199•25%=49.75
49.75+199=248.75
248.75•7.5%=18.65625
18.65625+248.75=267.40625
therefore the answer is $248.41

Aleonysh [2.5K]

<span>m = 4a + 2c

a = 25; c = 5

Replace a with 25. Replace c with 5.
Then evaluate the expression.

m = 4 * 25 + 2 * 5

m = 100 + 10

m = 110

Answer: 110 meatballs are needed.</span>
