Answer:
75 m
Step-by-step explanation:
The formula to apply here is;
d(t)= v₀t + at²/2
where
d=distance covered in time t
v₀=initial velocity in m/s
t=time taken in seconds
a=deceleration
Given that
v₀=8.00 m/s
t=15 sec
a= -0.400 m/s²
d(15)= 8.00 *15 + (-0.400*15²)/2
d(15)=120 + -90/2
d(15)= 120-45 =75 m
