During a race, a sprinter accelerated 1.8 m/s 2 in 2.5 seconds. The sprint increase with this amount of acceleration by 4.5 m/s.
<h3>What is acceleration?</h3>
Acceleration is the time rate of change of velocity.
Acceleration a = velocity v / time t
1.8 = v/2.5
v = 4.5 m/s
The sprint increase with this amount of acceleration by 4.5 m/s.

It might be c I'm not sure either. Hope I helped
The speed of bullet =
850 m/s
Distance given = 1 km = 1000m
S = D/t
t • S = D/t • t
St = D
St/S = D/S
t = D/S
t = 1000m/850m/s
t = 1.176 s
It will take the bullet 1.176 or about 1.18 seconds to go 1 km.
