Answer:
power=work done÷time taken
2×5=10
10÷10=1
ans 1J per second
Answer:
For the first one its about 25 feet
Explanation:
Idk its really weird because the ridges are making the quarter stand and therefore able to roll
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>
