Question

question 16
to do: retrieve a grade
10 n ← 3 kg → 25 n
what is the net force?
what is the acceleration?
check

Explanation:

Step1: Calculate Net Force

Forces in opposite directions: subtract. $F_{net} = 25\,\text{N} - 10\,\text{N} = 15\,\text{N}$ (right direction).

Step2: Calculate Acceleration

Use Newton's second law $F = ma \implies a = \frac{F}{m}$. Substitute $F = 15\,\text{N}$, $m = 3\,\text{kg}$. $a = \frac{15}{3} = 5\,\text{m/s}^2$ (right direction).

Answer:

Net Force: $15\,\text{N}$ (right)
Acceleration: $5\,\text{m/s}^2$ (right)
