Explanation:Watt=NM/s=J/s=kgm²/s³=hP
Answer :B,kgm²/s³
C
because an object need to be in motion to make any kind of movement
I'm not sure of the numbers sense I dont have a calculator right now. The formula is 1/2*M*V^2.
The difference between rotational motion and circular
motion is that rotational motion is the rotation of a body about it center
mass. The axis of rotation and the center mass could change. For circular
motion, the axis of rotation and the center mass does no change.
Answer: hello your question is incomplete below is the complete question
answer : Angular acceleration = 7.88 rad/s^2 ( clockwise )
minimum coefficient of friction = -0.2225
Explanation:
First step : we calculate acceleration at point O
a = rα
acceleration at point A
aA = ( 2r ) α = 2α
∑Fy ( force in y axis ) = mass of block * aA
∴ T = mBlock ( g - 2α )
= 8.7 ( 9.81 - 2α )
attached below is the remaining part of the solution
