The correct Answer is:
To calculate the work done by the car, we can follow these steps: ### Step 1: Identify the given values - Force (F) = \(2.5 \times 10^{10}\) N - Velocity (V) = 5 m/s - Time (T) = 2 minutes = 120 seconds ### Step 2: Calculate the distance traveled (S) Using the formula for distance: \[ S = V \times T \] Substituting the values: \[ S = 5 \, \text{m/s} \times 120 \, \text{s} \] Calculating this gives: \[ S = 600 \, \text{m} \] ### Step 3: Calculate the work done (W) Using the formula for work done: \[ W = F \times S \] Substituting the values: \[ W = (2.5 \times 10^{10} \, \text{N}) \times (600 \, \text{m}) \] Calculating this gives: \[ W = 2.5 \times 600 \times 10^{10} \] \[ W = 1500 \times 10^{10} \] ### Step 4: Express the result in scientific notation \[ W = 1.5 \times 10^{13} \, \text{J} \] ### Final Answer The work done is \(1.5 \times 10^{13}\) joules. ---
