Answer:
60 km
Explanation:
For an object (or a person, such as in this case) moving at constant speed, the speed is equal to the ratio between the distance travelled and the time taken:
where
v is the speed
d is the distance
t is the time taken
In this case, we have:
v = 120 km/h is the speed
t = 30 min = 0.5 h is the time taken
Therefore, we can rearrange the equation to find the total distance travelled:
Answer:
The bigger one. Ignoring air resistance, they will fall at the same speed, but the bigger one will hit first because it sticks out lower.
Explanation:
You have to find interia using I=mr^2.
m=75+10
radius = 11
Then you have to substitute in first formula above to find the angular speed.
14020=(75+10)x v x 11
v= 14020/ (85x11) = 15m/s
To find linear speed, use V=wr.
Equation: V = 11*1.363 = 15m/s = 33.6mi/hr
Hope this helps! :)
