Starting from rest, the Road Runner accelerates at 3 m/s for ten seconds. What is the final velocity of the Road Runner?
2 answers:
(3 m/s²) x (10 s) = <em>30 m/s</em>
His speed at the end of 10 sec is 30 m/s. We can't describe his velocity, because we have no information about the <em>direction</em> he's moving.
Answer
The answer to this question is 
Explanation
As we know that accelartion is the rate of change of velocity. So, it can be write as

where
is the final velocity
is the initial velocity
t is the time
a is the accelartion
as we konw

t = 10 s
From rest So,
= 0
= ?
Putting values




So, the right answe is

Answer:
1.67m/s
Explanation:
Total Distance to be travelled by a Runner=100m
Time Taken=10*6s
Speed=Distance/Time
=100/10*6=10/6=1.67m/s
Answer:
27,000 m
450 m/s
Explanation:
Assuming the initial velocity is 0 m/s:
v₀ = 0 m/s
a = 15 m/s²
t = 60 s
A) Find: Δy
Δy = v₀ t + ½ at²
Δy = (0 m/s) (60 s) + ½ (15 m/s²) (60 s)²
Δy = 27,000 m
B) Find: v_avg
v_avg = Δy / t
v_avg = 27,000 m / 60 s
v_avg = 450 m/s
