A car travels at 12 m/s. The car then accelerates at 3 m/s2 until it reaches a speed of 18m/s.
Use the formula: (final velocity)2 – (initial velocity)2 = 2 x acceleration * distance
Calculate the distance the car travels.
A
2 m
B
6 m
С
30 m
D
60 m

Answer:

С. 30 m

Explanation:

Given the following data;

Initial velocity, U = 12m/s

Final velocity, V = 18m/s

Acceleration, a = 3m/s²

To find the distance, we would use the third equation of motion;

V ² = U² + 2aS

Substituting into the equation, we have

18² = 12² + 2*3*S

324 = 144 + 6S

6S = 324 - 144

6S = 180

S = 180/6

Distance, S = 30 meters.
