If the hydraulic press starts from rest (Xi = 0) and (Vi = 0), after 300 seconds the position new speed is 2500 m/s. Explain the change in motion of the mobile and interpret the result of acceleration. Did it increase or decrease?

1. Identify the initial velocity \( V_i = 0 \) m/s and the final velocity \( V_f = 2500 \) m/s.

2. Note the period over which the change occurs is \( t = 300 \) s.

3. Use the formula for acceleration: a = \frac{V_f - V_i}{t}

4. Substitute the known values into the formula: a = \frac{2500 - 0}{300}

5. Simplify the expression: a = \frac{2500}{300} = \frac{25}{3} \, \text{m/s}^2

The solution reveals a constant acceleration of \( \frac{25}{3} \, \text{m/s}^2 \) indicating that the acceleration is increasing.
