Question
Transcribed Image Text:### Problem 1/1
**Statement:**
The sports car has a mass of 2.5 Mg and accelerates at 6 m/s², starting from rest.
**(Figure 1)**
**Figure 1 Description:**
The figure depicts an orange sports car with a person driving it. The car is accelerating to the right, which is indicated by a large arrow labeled \( \mathbf{F_D} \) pointing towards the left. This scenario represents the force of drag acting against the motion of the car.
The mass of the sports car is provided as 2.5 Mg (megagrams), which equals 2500 kg (since 1 Mg = 1000 kg). The acceleration of the car is given as \( 6 \, \text{m/s}^2 \). The car is starting from rest, implying an initial velocity of \( 0 \, \text{m/s} \).
**Note:** The temperature displayed at the bottom of the image is 86°F, with a clear weather condition icon.
![### Part A
**Problem Statement:**
If the drag resistance on the car due to the wind is \( F_D = (10v) \, \text{N} \), where \( v \) is the velocity in \( \text{m/s} \), determine the power supplied to the engine when \( t = 5 \, \text{s} \). The engine has a running efficiency of \( \epsilon = 0.63 \).
**Instructions:**
Express your answer to three significant figures and include the appropriate units.
