Answer:
Distance = 0.738 m
Explanation:
Solution:
<u> First convert Km/h into m/s.</u>
75 km/h * 1000 m/km * 1 hr/3600 sec = 20.8333 m/s
<u>According to third equation of motion: </u>
–
= 2 * acceleration * distance
<em> Vf= final velocity </em>
<em>Vi= initial velocity</em>
putting values in third equation of motion....
–
= 2 * (-30 * 9.8) * distance
note:
negative sign is due to deceleration
Distance = 0.738 m
