A motorcycle is moving at 18 m/s when its brakes are applied, bringing the cycle to rest in 4.7 s. To the nearest meter, how far
does the motorcycle travel while coming to a stop?
1 answer:
Answer:
the motorcycle travels 42.4 meters until it stops.
Explanation:
Vi= 18 m/s
Vf= 0 m/s
t= 4.7 sec
Vf= Vi - a*t
deceleration:
a= Vi/t
a= 18m/s / 4.7 sec => a=-3.82 m/s²
x= Vi*t - (a * t²)/2
x= 42.4m
