A machinist turns on the power on to a grinding wheel at time t = 0s. The wheel accelerates uniformly from rest for 10s and reaches the operating angular speed of 58 rad/s. The wheel is run at that angular velocity for 30s, and then power is shut off. The wheel slows down uniformly at 1.4 rad/s^2 until the wheel stops. What is the total number of revolutions made by the wheel in this situation ? A machinist turns on...
5) A machinist turns the power on to a grinding wheel, at rest, at time t=0 s. The wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 96 rad/s. The wheel is run at that angular velocity for 40 s and then power is shut off. The wheel slows down uniformly at 1.5 rad/s2 until the wheel stops. In this situation, the time interval of deceleration is closest to:
A machinist turns the power on to a grinding wheel, at rest, at time t = 0 s. The wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 40 rad/s. The wheel is run at that angular velocity for 34 s and then power is shut off. The wheel slows down uniformly at 2.8 rad/s2 until the wheel stops. In this situation, the time interval of deceleration is closest to:

13. A machinist turns the power on to a grinding wheel, at rest, at time t-0 s. The wheel accelerates uniformly with angular acceleration of 2.9 rad/s for 10 s when reaches its operating angular velocity. The wheel is run at that angular velocity for 15s and then power is shut off. The wheel slows down uniforml,y at 2.7 rad/s2 until the wheel stops. a. What is the total time the wheel is in...
A machinist turns the power on to a grinding wheel, which is at rest at time t = 0.00 s. The wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 86 rad/s. The wheel is run at that angular velocity for 32 s and then power is shut off. The wheel decelerates uniformly at 2.3 rad/s2 until the wheel stops. In this situation, the time interval of angular deceleration (slowing down) is closest to: 37 s...
A machinist turns on the power to a grinding wheel at time I Os. The wheel acceleraties unormuy from rest for 10 s and reaches the operating angular speed of 38 rads. The wheel is run at that angular speed for 30 s and then power is shut off. The wheel shows down uniformly at 2.1 rad/s2 until the wheel stops. A. In this situation, what is the angular acceleration of the wheel between t=0 sand 1 - 10 s?...
A machinist turns on the power on to a grinding wheel at time t = 0 s. The wheel accelerates uniformly from rest for 10 s and reaches the operating angular speed of 96 rad/s The wheel is run at that angular velocity for 40 s and then power is shut off. The wheel slows down uniformly at 1.5 rad/s^2 until the wheel stops. For how long a time after the power is shut off does it take the wheel...
A machinist turns on the power to a grinding wheel, which is at rest at t = 0.0 s. The wheel accelerates uniformly for 8.0 s and reaches the operating angular velocity of 80 rad/s. The wheel is then run at that angular velocity for 30 seconds and then the power is shut off. The wheel decelerates uniformly at 5.0 rad/s2 until the wheel stops. Through what total angle has the wheel turned? (a) 2400 radians (b) 3360 radians (c)...
QUESTION 1 A machinist turns off the power on a grinding wheel that is operating at an angular speed of 96 rad/s. The wheel slows down uniformly at 1.5 rad/s2 until it stops. Calculate the time it takes the wheel, in seconds, to come to a stop. Do not type in units.
I do not understand where and how i did wrong, please let me
know! Thank you!
P4 4) [8 pts] A block of mass 10.5 kg on an inclined plane (angle 0-320) ls attached to a cord that is wrapped around a wheel of radius 14.0 cm as in the figure. As the block slides the wheel turns and the cord unwinds. The acceleration of the block down the incline (which is frictionless) is measured to be 2.50 m/s2. Assume...
