Question

An object has an acceleration of 12.0 m/s/s. If the mass of

Answer 1

Answer:

New acceleration would be $36ms^{-2}$

Explanation:

Given ,

• The initial acceleration $a_{i}=12ms^{-2}$=

Let's assume the mass of the object to be '$mKg$,

Thus the net force $F$ acting on the object will be ,

$F=ma_{i}\\F=m*12\\F=12mN$

• Now if the mass reduces to one - third of the original value ,

           $m_{new}=\frac{m}{3}Kg$

And since the same force $F$ acts on it ,

$F=m_{new}a_{new}\\12m=\frac{m}{3} a_{new}\\a_{new}=12*3\\a_{new}=36ms^{-2}$

Thus,

$a_{new}=36ms^{-2}$
