During a race, a runner runs at a speed of 6 m/s. 2 seconds later, she is running at a speed of 10 m/s. What is the runner’s acc eleration? Show your work.
1 answer:
V o = 6 m/s, t = 2 s v = 10 m/s v = v o + a t a t = v - v o a = ( v - v o ) / t a = ( 10 m/s - 6 m/s ) / 2 s = 4 m/s / 2 s = 2 m/s² Answer:The runner`s acceleration is 2 m/s².

speed = 86km/hr
= 86000/3600
= 23.889m/s
time = 4.6s
acceleration = 23.889/4.6
a = 5.19m/s^2
Answer:
D because the molecules become solid so dont move as much 9 A because pressure would build up in the tank
Explanation:
Answer:
1.884 meters per second
Explanation:
s = d/t
d = C = 2πr = 2π(6) = 37.68 m
t = 20 s
s = (37.68 m)/(20 s)
s = 1.884 m/s
