If an object is launched at an angle of 28° with an initial velocity of 133 ft./s from a height of 6 feet how many seconds will

Tema [17]

Answer:

Hence after 3.98 sec i.e 4 sec Object will hit the ground .

Step-by-step explanation:

Given:

Height= 6 feet

Angle =28 degrees.

V=133 ft/sec

To Find:

Time in seconds after which it will hit the ground?

Solution:

<em>This problem is related to projectile motion for objec</em>t

First calculate the Range for object and it is given by ,

$R=v^2Sin$ (2Ф)/ $g$

Here R= range g= acceleration due to gravity =9.8 m/sec^2

1m =3.2 feet

So 9.8 m, equals to 9.8 *3.2=31.36 ft

So g=31.36 ft/sec^2. and 2Ф=2(28)=56

$R=133^2*Sin(56)/31.36$

$R=14664.84/31.36$

$R=467.62$ fts

Now using Formula for time and range as

$R=VxT$

Vx is horizontal velocity

$Vx=V*cos$ Ф

$Vx=133*cos$ (28)

$Vx=117.43$ ft/sec

So above equation becomes as ,

$467.62=117.43*T$

$T=467.62/117.43$

$T=3.98 sec$

T is approximately equals to 4 sec.

There are 3 workers at the Gold Trinkets Company. Two of the workers can each

Llana [10]

Answer:

Step-by-step explanation:

So first let us break how much trinkets one worker can make and find out the time frame. So the first two workers each can make a trinket in 90 seconds, 90/2 is 45 (seconds) for 1 worker. And the third worker takes 10 seconds longer, so 45+10 is 55 seconds for the third worker to make 1 trinket. There are 60 minutes in a hour, 60x60(seconds) is 3600 seconds in an hour. But here we will have to do 3600/100, because we forget about the individual time and focus on the combined time. So we add 10 more to 90, and now get 3600/100, which gives us out result of 36 trinkets made in an hour

sorry it took long i burnt my brain for this one
