Question

a 25 kg object experiences a force of 50 n for 4 seconds. if it starts from rest, what will be its final velocity? * 2 points choose

Explanation:

Step1: Calculate acceleration

Using Newton's second law \(F = ma\), solve for \(a\).
\(a=\frac{F}{m}=\frac{50\ N}{25\ kg}=2\ m/s^{2}\)

Step2: Calculate final velocity

Using the kinematic equation \(v = v_{0}+at\). Since \(v_{0} = 0\) (starts from rest), \(v=at\).
\(v=(2\ m/s^{2})\times4\ s = 8\ m/s\)

Answer:

\(8\ m/s\)
