Answer:
mid point=(x1 + x2)/2 (y1 + y2)/2
(-5+5)/2 and (-7+4)/2
0 and 1.5
midpoint=(0,1.5)
A ) v = v o + g t
h = v o * t + g t² /2
10 m = 9.81 m/s² * t² / 2
9.81 t² = 20
t² = 2.038
t = 1.4278 s
v = 0 + 9.81 * 1.4278
v = 14 m/s
b ) v o = 14 m/s
v = v o² + 2 a d
0 = 14² + 2 a * 2.9
196 = - 5.9 a
a = 196 : ( - 5.9 )
a = - 33.79 m/s² ( the magnitude of his acceleration while in water )
c ) The total amount of force exerted on the swimmer in water:
F = m * a = 65 kg * 33.76 m/s²
F = 2,196.55 N
Answer:
A.78
Step-by-step explanation:
DONT TRUST ME
4 less than 1/2 of x is 37 less than 2 of x
-4+(x/2)=-37+2x
add 37 to both sides
33+(x/2)=2x
times 2 both sides
66+x=4x
minus x both sides
66=3x
divide 3 both sides
22=x
Answer:
4560
Step-by-step explanation:
Well, first we need to understand how different time formats (for lack of a better word) are related in terms of seconds.
1 minute has 60 seconds
I hour has 3600 seconds
1 day has 86400 seconds
1 week has 604800 seconds
Now, with this information at hand, you can find out how many seconds are in X minutes or X days or X months or a year (and so on).
As for your question, we know that one minute has 60 seconds therefore 76 minutes will have (76x60) seconds
