Answer:
-30 m is the answer
Step-by-step explanation:
Using the formula of newtons second law
F=ma
F=force=9500N=9500kg.m/s^
m=mass=1000 kg
a=acceleration=?m/s^
a=F/m
a=(9500kg.m/s^)/(1000kg)= 9.5m/s^
Now we can easily solve it by kinematic equation
v^=u^+2as
v = final velocity = 15.9 m/s
u = initial velocity = 30 m/s
a = acceleration = 9.5 m/s²
s = displacement = ? m
s = (v² - u²)/2a
s = ((15.9 m/s)² - (30 m/s)²)/(2 × 9.5 m/s²) = -34.06 m = -30 m (rounded to one significant figure)
In this, Negative displacement means the car is slowing down.
