Solve science problem

Step 1: Identify the given information. The problem states that a 2.0 kg object is moving at 5.0 m/s.

Step 2: Determine what needs to be calculated. We need to find the kinetic energy of the object.

Step 3: Recall the formula for kinetic energy. The formula for kinetic energy ($KE$) is: $KE = \frac{1}{2}mv^2$ where $m$ is the mass and $v$ is the velocity.

Step 4: Substitute the given values into the formula. $m = 2.0 \, \text{kg}$ $v = 5.0 \, \text{m/s}$ $KE = \frac{1}{2}(2.0 \, kg)(5.0 \, m/s)^2$

Step 5: Calculate the square of the velocity. $(5.0 \, m/s)^2 = 25.0 \, m^2/s^2$

Step 6: Perform the multiplication. $KE = \frac{1}{2}(2.0 \, kg)(25.0 \, m^2/s^2)$ $KE = (1.0 \, kg)(25.0 \, m^2/s^2)$ $KE = 25.0 \, kg \cdot m^2/s^2$

Step 7: State the final answer with the correct units. The unit $\text{kg} \cdot m^2/s^2$ is equivalent to Joules (J). $KE = 25.0 \, \text{J}$

The kinetic energy of the object is 25.0 J.
