A 1kg engine rotates at 1 rad/sec about a point on a 3meter wire. The engine produces an acceleration of 1 rad/sec^2 and is fird for 2 minutes.
a) What is the ω at the end of 2 minutes?
b) what's the tension in the wire at the end of 2 min.?
c) how far will the engine travel in meters while it's accelerating?
d) what's the Kinetic Energy of the engine after it shuts down?
a)ω=radius/Time or ω= θ/Time
d) KE=1/2(Ι)(angluar acceleration)(T)^2
The Attempt at a Solution
ω=3/120= 0.25 rad/sec
need help with b&c and with corroborating a&d!
