Question

if the block in the picture has an acceleration of 5 m/s2, what would be the blocks mass? 25 kg 2.5 kg 0.4 kg 2 kg

Explanation:

Step1: Use Newton's second law

Newton's second law is \(F = ma\), where \(F\) is force, \(m\) is mass and \(a\) is acceleration.

Step2: Rearrange the formula to find mass

We can rearrange \(F = ma\) to \(m=\frac{F}{a}\).

Step3: Substitute the values

From the problem, \(F = 25N\) and \(a = 5m/s^{2}\). Substituting these values into \(m=\frac{F}{a}\), we get \(m=\frac{25}{5}\).

Step4: Calculate the mass

\(m=\frac{25}{5}=5kg\)

Answer:

\(5kg\)
