At t=0 at grinding wheel has an angular velocity of 24.0 rad/s. It has a constant angular acceleration of 30.0 rad/ s2 until circuit breaker trips at t=2.00s. From then on, it turns through 432 rad as ut coasts to a stop at constant angular acceleration. a) through what total angle did the wheel...
If one ball was thrown down with an initial velocity and another ball was thrown up with the same initial velocity. a) Which would have greater speed when it reaches the ground? b)Which has a greater displacement? c) Which ball will hit the ground first? d) Which traveled a greater distance...
Is it possible for an object to be slowing down while the magnitude of acceleration increasing? And is it possible for an object to be speeding up while its acceleration is decreasing?
I am a bit confused about the meaning of increasing and decreasing acceleration. I mean what makes an...
