Answer:
2 m/s²
Explanation:
Given:
v₀ = 0 m/s
v = 20 m/s
t = 10 s
Find: a
a = (v − v₀) / t
a = (20 m/s − 0 m/s) / 10 s
a = 2 m/s²

Let's start by finding the time it takes for the dog to reach a velocity of
m/s.
We can use the following equation, where
is initial velocity,
is final velocity,
is time, and
is acceleration.

We're trying to solve for
first, so divide both sides by
.

Substitute in the known values.



Now, we can use the following formula to find the distance.

Substitute in the known values.

Anything multiplied by
is

Just simplify from there.




The power P in watts (W) is equal to the energy E in joules (J), divided by the time period t in seconds (s):
P(W) = E(J) / t(s)
2.78 Watts
