Answer:
185.3m
Explanation:
Given parameters:
Initial velocity = 10m/s
Final velocity = 21m/s
Time = 12s
Unknown:
Total distance traveled by the car = ?
Solution:
To solve this problem, we use that appropriate motion equation:
v² = u² + 2as
v is the final velocity
u is the initial velocity
a is the acceleration
s is the unknown distance
t is the time taken;
acceleration = [tex]\frac{v - u}{t}[/tex]
a = [tex]\frac{21 - 10}{12}[/tex] = 0.92m/s²
now;
v² = u² + 2as
21² = 10² + 2(0.92)(s)
441 = 100 + 1.84s
441 - 100 = 1.84s
s = 185.3m
