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}
