Answer:
The car must travel 51.34 m for its speed to reach 2.7 m/s
Explanation:
Mass of car = 2.9 x 10³ kg
Forward force = 1148 N
Resistive force = 941 N
Total force = 1148 - 941 = 207 N
We know
Force = Mass x Acceleration
207 = 2.9 x 10³ x Acceleration
Acceleration = 0.071 m/s²
Now we have equation of motion, v² = u² + 2as
Initial velocity, u = 0 m/s
Final velocity, v = 2.7 m/s
Acceleration, a = 0.071 m/s²
Substituting
v² = u² + 2as
2.7² = 0² + 2 x 0.071 x s
s = 51.34 m
The car must travel 51.34 m for its speed to reach 2.7 m/s
