Question

an object of mass 18.0 kg subjected to a non - zero net force moves with an acceleration of 1.5 m/s². (a) determine the net force (in n) acting on it. (enter the magnitude only.) n (b) what acceleration (in m/s²) would a 36.0 - kg object have if the same net force is applied to it? m/s²

Explanation:

Step1: Use Newton's second law for part (a)

According to Newton's second law $F = ma$, where $m = 18.0$ kg and $a=1.5$ m/s².
$F=18.0\times1.5$

Step2: Calculate the force

$F = 27$ N

Step3: Use Newton's second law for part (b)

We know $F = 27$ N and $m = 36.0$ kg. From $F=ma$, we can solve for $a$, so $a=\frac{F}{m}$.
$a=\frac{27}{36.0}$

Step4: Calculate the acceleration

$a = 0.75$ m/s²

Answer:

(a) 27
(b) 0.75
