If the mass of a
mixer [17]

Answer:

The final acceleration becomes (1/3) of the initial acceleration.

Explanation:

The second law of motion gives the relationship between the net force, mass and the acceleration of an object. It is given by :

F=ma

m = mass

a = acceleration

According to given condition, if the mass of a  sliding block is tripled while a constant net force is applied. We need to find how much does the acceleration decrease.

a=\dfrac{F}{m}

Let a' is the final acceleration,

a'=\dfrac{F}{m'}

m' = 3m

a'=\dfrac{F}{3m}

a'=\dfrac{1}{3}\times \dfrac{F}{m}

a'=\dfrac{1}{3}\times a

So, the final acceleration becomes (1/3) of the initial acceleration. Hence, this is the required solution.

How long does it take an airplane to fly 1200 miles if it maintains a speed of 300 miles per hour
sdas [7]

Answer:

The answer is

<h2>4 hrs</h2>

Explanation:

To find the time taken we use the formula

t =  \frac{d}{v}  \\

where

d is the distance covered

v is the velocity

t is the time

From the question

d = 1200 miles

v = 300 mi/hr

We have

t =  \frac{1200}{300}  =  \frac{12}{3}  \\

We have the final answer as

<h3>4 hrs</h3>

Hope this helps you
