Question

ignoring friction, what is the mass of an object accelerating at 1.8m/s2 to which an unbalanced force of 42 Newtons has been applied?​

Answer 1

Explanation:

Newton's second law:

F = ma

42 N = m (1.8 m/s²)

m = 23 kg

Answer 2

• Force=42N
• Acceleration=1.8m/s^2

Using newtons second law

$\boxed{\sf Force=Mass\times Acceleration}$

$\\ \sf\longmapsto Mass=\dfrac{Force}{Acceleration}$

$\\ \sf\longmapsto Mass=\dfrac{42}{1.8}$

$\\ \sf\longmapsto 23.3kg$

$\\ \sf\longmapsto 23kg(Approx)$
