At t=0 a grinding wheel has an angular velocity of 21.0rad/s . It has a constant angular acceleration of 35.0rad/s^2 until a circuit breaker trips at time t = 2.50s . From then on, it turns through an angle 440rad as it coasts to a stop at constant angular acceleration.
(A) Through what total angle did the wheel turn between t=0 and the time it stopped?
(B) At what time did it stop?
(C) What was its acceleration as it slowed down?
Find the speed of a satellite in a circular orbit around the earth with a radius 4.01 times the mean radius of the earth; RE 6.37E+3km; ME 5.98E+24kg
As the drawing shows, the bullet puts a hole in a window of another building and hits the wall that faces the window. h is 0.54 m and d is 8.0 m. Assume that the bullet does not slow down as it passes through the window. Evaluate the Distance H
Two light sources are used in a photoelectric experiment to determine the work function for a particular metal surface. What stopping potential would be observed when using light from a red lamp
At time t = 0 s, a wheel has an angular displacement of zero radians and an angular velocity of +15 ras/s. The wheel has a constant acceleration of -0.45 rad/s2. In this situation, the maximum value of the angular displacement, in rad, is closest to:
