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:
14°
Step-by-step explanation:
180-152=28
28÷2=14
Brady needs three strips that each represent one fourth (1/4). He needs to line them up end to end. The new long strip he has created represents 3/4.
Next Brady needs seven strips that each represent one eighth (1/8). He needs to line them up end to end. The new long strip he has created represents 7/8.
If the two long strips he created were equal then 3/4 would equal 7/8 but as they are not equal this is not the case. Since the strip for 7/8 is longer, the fraction 7/8 is greater than 3/4.
