Answer:
d = .076 m
Explanation:
The time for frog A can be calculated from equation of motion

where v_f is final velocity, a is acceleration due to gravity
so from given data we have

t = 0.112 sec
Now we will use that time for frog B


(Note its positive)
For the displacement


d = .076 m
Answer:
A car engine has more power than a horse because a car engine does the same amount of work in time. Yasmin and Raj each had 10 boxes of equal weight to stack next to each other on the same shelf, at the same height and in the same arrangement. Yasmin completed the task in 2 minutes, while Raj took 3 minutes to stack his boxes. Raj applied less power than Yasmin because his stacking took more time to do the same amount of work.

Bacteria, Hydra, Copperheads, Blackworms, and Strawberries
Explanation:
Answer:
ac = 72 m/s²
Fc = 504 N
Explanation:
We can find the centripetal acceleration of the hammer by using the following formula:

where,
ac = centripetal acceleration = ?
v = constant speed = 12 m/s
r = radius = 2 m
Therefore,

<u>ac = 72 m/s²</u>
<u></u>
Now, the centripetal force applied by the athlete on the hammer will be:

<u>Fc = 504 N</u>
I notice that the energy how it’s transferred it goes down slowly and the heat waves slowly rise up when conducting air
