Question

A force of 4 N accelerates a mass at 1 m/s^. When the force applied is reduced to 2 N what is the new value of acceleration​

Answer 1

Step-by-step explanation:

hope u will understand ,thankyou

Answer 2

Step-by-step explanation:

Given:A force of 4 N accelerates a mass at 1 m/s². When the force applied is reduced to 2 N.

To find: what is the new value of acceleration?

Solution:

Formula used:

$\boxed{\bold{F=ma}}$

where,

F = Force

m= mass

a = acceleration

Step 1: Find the value of mass

$F = ma \\ \\ m = \frac{F}{a} \\ \\ m = \frac{4}{1} \\ \\ m = 4 \: kg$

Step 2: Find the value of acceleration if force is 2N

$F= ma \\ \\ a = \frac{F}{m} \\ \\ a = \frac{2}{4} \\ \\ a = \frac{1}{2} \\ \\ or \\ \\ a = 0.5 \: m/ {s}^{2}$

Final answer:

New acceleration is 0.5 m/s².
