After 30 s, a runner is sprinting at 3 m/s. but, 10 s later, the runner is sprinting at 3.8 m/s. what is the runner's acceleration during this time?

0.08m/s²

Step-by-step explanation:

Acceleration is a rate, a rate of Velocity over Time. To measure it you have to know how fast someone,  or something in this case sprints at a given interval of time.

t1=30  V1=3m/s

t2=40  V2=3.8m/s

So, with all data collected. Let's calculate it:

a=Δv/Δt

a= 0.08 m/s²

At 0.08 meters per square second the sprinter accelerates over a ten seconds period.

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5

step-by-step explanation:

0

step-by-step explanation:

equals the constant of proportionality.
