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 ,
(2Ф)/
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


fts
Now using Formula for time and range as

Vx is horizontal velocity
Ф
(28)
ft/sec
So above equation becomes as ,


T is approximately equals to 4 sec.

Answer:
b. Kinsey must save $72 per month to achieve her goal.
Step-by-step explanation:
<em>Goal over 16 months:</em> $60 x 16 = $960
<em>Collected after 11 months:</em> $600
- $360 still needed
- 5 months lefts
$360 ÷ 5 = $72
Answer:
Step-by-step explanation:
To get the other angles you need to do this
110+80+x+x=360
190+2x=360
2x=360-190
2x=170
X=170÷2
X=85
