Answer:
Centripetal Acceleration 18.75 m/s^2, Rotational Kinetic Energy 843.75 J
Explanation:
a Linear acceleration (we cant find tangential acceleration with the givens so we will find centripetal)
a= ω^2*r
ω= 300rev/min
convert into rev/s
300/60= 5rev/s
a= 18.75m/s^2
b) use Krot= 1/2 Iω^2
plug in gives
1/2(30*2.25)(25)= 843.75 J
Answer:
Freezing
Explanation:
I am pretty sure that the energy particles slow down when they freeze, making it the only one in which energy does NOT increase. Hope I helped.
Answer: 588.9 m/s
Explanation:
Given that :
θ = 30°
Height, h = 3400m
Time, t = 10 seconds
From trigonometry ;
Tanθ = opposite / hypotenus
Tan 30 = 3400 / x
x tan 30 = 3400
0.5773502x = 3400
x = 3400 / 0.5773502
x = 5888.9727
Recall ;
Speed = Distance / time
Speed = 5888.9727 / 10
Speed = 588.897 m/s
Speed = 588.9 m/s
