During the swing of a bat through an arc of 2 rad(114.6degrees) what would be the...
A baseball player swings a bat. The bat is 1.5m from the fulcrum (axis of rotation) to the top of the bat. The start angle of the swing is 70° and the angle at which the ball is hit is 190°. The start time is 0s and the end time is 0.5s. The bat swings in the negative direction. What is the linear distance traveled by the end (top) of the bat?
A golfer’s hands move through an arc length of 10 cm during a putt. What arc length does the head of the putter move through if the hands are 50 cm from the axis of the rotation and the putter head is 150 cm from the axis of rotation?
The swing phase of the right leg last 0.4 seconds, during this time the right knee joint has an average velocity of 250 deg/sec. On the left side the swing phase of 0.36 seconds and the left knee joint has an average velocity of 262 deg/sec. If the distance between the foot and the knee joint is 0.38 meters for both the right and left sides, which side would have a longer step length (linear distance traveled by the foot)?
1. IF a discus thrower rotates through 45 degree of a turn in 0.11 s and the distance from the axis of rotation to the center of the discus if 1.22 m, calculate the average linear velocity of the discus. A. 499 m/s B. 502 m/s C. 8.7 m/s D. 9.0 m/s 2. A object is spinning at a constant angular velocity of 13.9 rad/s. If it spins for 1.9 s, what is the angular distance traveled? A. 26.4 rad...
A baseball placed on a tee was hit by a bat 40 cm from the bat’s axis of rotation. If the angular velocity of the bat was 90 rad/s at the instant contact, what was the linear velocity of the ball when the bat contacted the ball (Assume that the linear velocity of the ball is the same as the linear velocity of the bat at the point at which it is struck)? If the baseball was hit 1 m...
1.) a ball of radius 20 cm starts from rest and accelerates at 0.2 rad/s^2, through what linear distance does it roll in 10 seconds? 2.) a wheel rotating at 12 rpm speeds up to 22 rpm in 5 seconds. what is the linear acceleration of the wheel if the radius is 3m? (PLEASE SOLVE IN DETAIL, THANK YOU IN ADVANCE )
6. A baseball bat has a mass of 0.85 kg. If the player holds that bat near the handle, the distance from the hands (axis of rotation) to the center of mass of the bat is 0.75 m. What is the moment of inertia for the bat? If the player chokes up 5 cm (0.05 m), what would be the new moment of inertia for the bat (subtract this 0.05 m from the 0.75 m).
7. A pendulum bob swings through an arc 40 inches long on its first swing.
