Answer:

2.96×10⁸ m/s

Explanation:

Speed = distance / time

v = (2 × 3.85×10⁸ m) / (2.60 s)

v = 2.96×10⁸ m/s

Nataly [62]

Answer:

principle of contiguity

Explanation:

The Law of Contiguity states that after events occur together (in spatio-temporal proximity), the re-occurrence of just one of the event awakens the 'memory' of the others. It is employed in a great number of scientific theories of learning, memory, and knowledge.

A particle moving along the x-axis has its velocity described by the function vx =2t2m/s, where t is in s. Its initial position
Illusion [34]

Answer:

Follows are the solution to this question:

Explanation:

In point a:

Place of particles

X(t)=\int V_{x}(t)dt

       =\int 2t^{2}dt\\\\=\frac{2}{3}t^{3}+C

\to t=0\\\\ \to X(0)=2.3 \ m

\to X(0)=0+C\\\\ \to C=2.3\  m

\to X(t)=( \frac{2}{3})t^3 + 2.3\\\\ \to t=2.2\\\\\to X=( \frac{2}{3})\times 2.2^3 +2.3 \\\\

        = \frac{2}{3}\times 10.648 +2.3\\\\= \frac{21.296}{3}+2.3\\\\  = 7.09+2.3\\\\ =9.39\\\\ =9.4\ m

In point b:

when t=2.2 \ s

the Particle velocity  (V)=2 \times 2.22 =9.68\  \frac{m}{s}

In point c:

Calculating the Particle acceleration:

\to a=\frac{dV}{dt} =4\ t\\\\\to t=2.2 \ s\\\\\to a=4\times 2.2  =8.8 \ \frac{m}{s^2}
