A particle undergoes a constant acceleration of 3.90 m/s2. After a certain amount of time, its velocity is 12.2 m/s. (Where appl
Law Incorporation [45]

Answer:

s_{f} = 14.312 m

Explanation:

Since the particle is experimenting a constant acceleration, the displacement can be found by using this formula:

v_{f}^{2} = v_{o}^{2} + 2 \cdot a \cdot (s_{f} - s_{o})

Since s_{o} = 0 m, the equation is simplified to this form:

v_{f}^{2} = v_{o}^{2} + 2 \cdot a \cdot s_{f}

Then, the displacement is now isolated:

s_{f} = \frac{v_{f}^{2}-v_{o}^{2}}{2 \cdot a}

Terms are replaced herein:

s_{f} = \frac{(12.2 \frac{m}{s})^{2}-(6.1 \frac{m}{s})^{2}}{2 \cdot (3.90 \frac{m}{s^{2}}) } \\s_{f} = 14.312 m

insens350 [35]

Answer:

774.8 secs

Explanation:

distance(d)= speed(v)* time(t)

calculate speed:

refractive index = speed of light (c)/ speed of light in medium (v)

1.56 = 3*10^8*v

v=192307692.3 m/s

d = v *t

t = d/v

on substituting values:

t = 774.8 secs
