Answer:
12.5% profit
Step-by-step explanation:
- he spents $8000 (1000×8)
- HE sells 900 of them for $10 making $9000, his profit is $1000 .
- profit divided by original price multiplied by 100 . . (1000/8000×100)
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:
$18.63
Step-by-step explanation:
first divide 60 by 29 to get 2.07 then you multiply 9 by 2.07 and get 18.63
