Answer:

v=20\frac{m}{s}

Explanation:

The velocidty is defined as the change of position during an interval of given time. Therefore, it is calculated by dividing the distance traveled by the time taken to do it:

v=\frac{x}{t}

Replacing the given values:

v=\frac{38m}{1.9s}\\v=20\frac{m}{s}

A student performs this experiment and measures the bar to have a mass of 150g and length of 36cm. What is the moment of inertia
Ugo [173]

Answer:

The moment of inertia of the bar is 45\times10^{-4}\ kg-m^2

Explanation:

Given that,

mass of bar = 150 g

Length l = 36 cm

We need to calculate the moment of inertia of the bar

Using formula of moment inertia

I=\dfrac{1}{12}Ml^2

Where,

M = mass of the bar

L = length of the bar

Put the value into the formula

I=\dfrac{1}{12}\times150\times10^-3\times36\times10^{-2}

I=45\times10^{-4}\ kg-m^2

Hence, The moment of inertia of the bar is 45\times10^{-4}\ kg-m^2

A negative velocity, approaching zero, represents a negative acceleration. True or False
ruslelena [56]

Answer:

False.

Explanation:

Lets assume our positive direction to the right (this reasoning works for any direction). A negative velocity would then be then directed to the left. If it varies as such that it aproaches to zero, it means that the variation is directed to the right, and that is where the direction of the acceleration must be pointing. In other words, its losing its velocity, so the acceleration must point opposite to the velocity. Then it means the acceleration is positive.
