Question

A net force of 30N is applied to an object, causing it to accelerate at 20 m/s^2. What is the mass
of the object?

Answer 1

• Force=30N
• Acceleration=20m/s^2

$\\ \sf\longmapsto F=ma$

$\\ \sf\longmapsto m=\dfrac{F}{a}$

$\\ \sf\longmapsto m=\dfrac{30}{20}$

$\\ \sf\longmapsto m=1.5kg$

Answer 2

Explanation:

• Force(F)= 30N
• Acceleration (a)= 20m/s²
• Mass(m)= ?

We know that,

• F=ma
• m=F/a
• m=30/20
• m=1.5 kg

Hence, the mass of the body is 1.5 kg.
