1 answer:

8 0

Newton's motion laws state that if an object is at rest or in movement, it will tend to maintain its basal state.

<h3>What are Newton's motion laws?</h3>

Newton's motion laws are a set of scientific statements aimed at explaining the physical property of movement.

These laws explain why objects in movement tend to maintain the same velocity for a short period of time.

In conclusion, Newton's motion laws state that if an object is at rest or in movement, it will tend to maintain its basal state.

A Ping-Pong ball has a mass of 2.3 g and a terminal speed of 9.3 m/s. The drag force is of the form bv2 What is the value of b?

Fed [463]

Answer:

The value is $b = 0.00026 \ kg / m$

Explanation:

From the question we are told that

The mass of the Ping-Pong is $m = 2.3 \ g = 0.0023 \ kg$

The terminal speed is $v = 9.3 \ m/s$

The drag force is $bv^2$

Generally the resultant force on the Ping- Pong is mathematically represented as

$F = mg - bv^2$

when terminal velocity is attained , the resultant force is zero so

$0 = mg - bv^2$

=> $b = \frac{m * g}{v^2}$

=> $b = \frac{0.0023 * 9.8}{ 9.3 ^2}$

=> $b = 0.00026 \ kg / m$
