Answer to Question #131256 in Mechanics | Relativity for Alen Andaya

Question

A certain force accelerates a 4.2kg mass by 5m/s2. What would be the acceleration of 3.4kg mass when the same forces acts on it?

Answer 1

$a_1 = 5 m/s^2$

$m_1 = 4.2 kg$

$m_2 = 3.4 kg$

The equation for acceleration:

$a = \frac{F}{m}$

$F = a\times m$

$F = 5\times 4.2 = 21 N$

$a_2 = \frac{21 N}{3.4 kg} = 6.17 m/s^2$

Answer: 6.17 m/s²
