Answer

\Delta KE = KE_{final} - KE_{initial}$$

Here are the solutions to both problems:

: If a certain force acts on an object and changes its kinetic energy from $65 \text{ J}$ to $130 \text{ J}$ , then work done by the force will be:

Step 1: Apply the Work-Energy Theorem. The work done ( $W$ ) by a force is equal to the change in kinetic energy ( $\Delta KE$ ). $W = \Delta KE = KE_{final} - KE_{initial}$ Given: Initial kinetic energy ( $KE_{initial}$ ) = $65 \text{ J}$ Final kinetic energy ( $KE_{final}$ ) = $130 \text{ J}$
