Answer:

a). 1.18 m

b). 0.67 s

c). 3.5 \frac{m}{s}

Explanation:

a=-g*sen*(32)= -5.1932 \frac{m}{s^{2} }= -5.2 \frac{m}{s^{2} }

a).

V_{f} ^{2} =V_{i} ^{2}+2*a*d , V_{f} =0, V_{i} =3.5\frac{m}{s }

d= \frac{3.5^{2}\frac{m}{s}  }{2*5.2\frac{m}{s^{2} } } = 1.179426 m\\d=1.18m

b).

V_{f} = V_{i} + a *t , V_{f} =0, V_{i} =3.5\frac{m}{s }

0 = 3.5 + 5.2*t

t= \frac{3.5 \frac{m}{s} }{5.2 \frac{m}{s^{2} } }

t= 0.67 s

c).

V_{f} ^{2} =V_{i} ^{2}+2*a*d, V_{i} =0

V_{f} ^{2} = 0 + 2* 5.2 \frac{m}{s^{2} } * 1.18m = 12.272 \frac{m^{2} }{s^{2} }

V_{f} =\sqrt{12.272 \frac{m^{2} }{s^{2} } } =3.503 \frac{m}{s}

Objectivism is a philosophy that stresses the external rather than the internal. They believe that most things exist outside of what people know or feel and that the truth especially exists beyond what people know. 
The phrase "clear sight and clean soul" supports this belief because in order to see things that are outside of yourself you need to have clear sight, the ability to see things beyond what you already know and believe. You also need to have a clean soul in order to look at things with a fresh perspective.
