Answer:

4 2/3 m/s

Explanation:

first thing to find the average acceleration is to figure out what the increase in speed was, we can do that by subtracting the original speed from the speed after accelerating, that looks like:

40 - 12 = 28

so the lizard accelerated 28 m/s in 6 seconds, to find the average increase in m/s every second, we divide the m/s by the seconds, which gives us:

28 / 6 = 4.66 = 4 2/3 m/s

Answer:

\boxed {\boxed {\sf \frac{14}{3} \ or \ 4.6667 \ m/s^2}}

Explanation:

Acceleration can be found using the following formula.

a=\frac{v_f-v_1}{t}

where v_f is the final velocity, v_i is the initial velocity and t is the time.

The lizard started at 12.0 m/s and accelerated up to its final velocity of 40.0 m/s in 6 seconds.

Therefore:

v_f= 40.0 \ m/s \\v_i= 12.0 \ m/s \\t= 6 \ s

Substitute the variables into the formula.

a=\frac{40.0 \ m/s - 12.0 \ m/s}{6 \ s}

Solve the numerator first and subtract.

  • 40.0 m/s - 12.0 m/s= 28 m/s

a=\frac{ 28 \ m/s}{6 \ s}

Divide.

a= \frac{14}{3} \ m/s/s= \frac{14}{3} \ m/s^2

a=4.66667 \ m/s^2

The lizard's average acceleration is <u>14/3 or 4.66667 m/s²</u>

In the figure below the pulley is a solid disk of mass M and radius R with rotational inertia MR 2/2. Two blocks one of mass m a
matrenka [14]
Assuming you are looking for the acceleration a:

1.m_1a = T_1 -m_1g
2.m_2a = m_2g - T_2
where T is the tension and a is the acceleration of the blocks. The acceleration of the two blocks and the acceleration of the pulley must be equal.

The torque on the pulley is given by:
3.\tau = \overrightarrow r \times \overrightarrow F = (T_2 - T_1)R = I\alpha = \frac{1}{2} MR^2 \frac{a}{R}
where I = \frac{1}{2} mR^2 and a = \alpha R.

Combining the three equations:
T_2 - T_1 = \frac{1}{2} Ma \\ m_2g - m_2a -m_1g - m_1a = (m_2-m_1)g - (m_1 + m_2)a = \frac{1}2}Ma \\ \\ a = \frac{(m_2 - m_1)g}{m_1 + m_2 + \frac{1}{2}M }
