The angular speed of a rotating platform changes from W equals 2.8 rads/S to W equals 6.8 rad/S at a constant rate as a platform moves through an angle 5.5 rad. The platform has a radius of R equals 28 cm w0=2.8rad/s w=6.8rad/s 0=5.5 radians r=28cm calculate the angular acceleration of the platform a in rad per second squared calculate the tangential acceleration, aT in meters per second squared of a point on the surface of the platform at the outer edge
A wheel (of radius 0.5 meters) spins with an angular velocity of 2 radians per second (rad/s). If this wheel were rolling on the ground without sliding, how fast would the wheel be traveling? O 1 m/s O 0.5 m/s It's not this one. O 2 m/s
A pitcher throws a curveball that reaches the catcher in 0.64 s. The ball curves because it is spinning at an average angular velocity of 260 rev/min (assumed constant) on its way to the catcher's mitt. What is the angular displacement of the baseball (in radians) as it travels from the pitcher to the catcher? Number Units
The diameters of the main rotor and tail rotor of a single-engine helicopter are 7.53 m and 1.04 m, respectively. The respective rotational speeds are 456 rev/min and 4,140 rev/min. Calculate the speeds of the tips of both rotors MAIN ROTOR M/S? TAIL ROTOR M/S Compare these speeds with the speed of sound, 343 m/sv main rotor = ? V SOUND tail rotor = V SOUND
A merry-go-round rotates from rest with an angular acceleration of 1.88 rad/s?. How long does it take to rotate through (a) the first 3.24 rev and (b) the next 3.24 rev? (a) Number i Units (b) Number i Units
1. A baseball pitcher brings his arm forward during a pitch, rotating the forearm about the elbow. If the velocity of the ball in the pitcher's hand is 31 m/s and the pitcher's forearm is 0.3 m long, what is the angular velocity of the forearm? Hint: Drawing a small cartoon could be helpful. rad/s @=
