A 0.7 kg flying pig travels in a circle hanging from a 20 m cord that makes an 11 degree angle with the vertical. What is the flying pigs tangential velocity?
(40 pts) The 1.8 kg tetherball travels in a circle hanging from a 0.8-m cord that makes a 11° angle with the vertical. What is the tangential velocity of the tetherball?
An airplane is flying at constant speed v=54 m/s in a horizontal circle of radius r=11 m. The lift force on the wings due to the air is perpendicular to the wings. At what angle to the vertical must the wings be banked to fly in this circle? θ = __________
A block of mass m is hanging from a cord that is wrapped around a pulley with radius R and moment of inertia I. When the block is released from rest, the pulley will rotate counterclockwise. Part A Solve for the acceleration of the block (your answer can include m,g,R, and I) Part B Draw a free body diagram showing the forces that act on the block Part C What happens to the acceleration of the block if the moment...
a) Tetherball is a game that uses a ball hanging from a string attached to the top of a post, where the ball is sent flying around in the tangential direction. Assume a uniform gravitational acceleration g pointed downward. This is an example of what is known as a “conical pendulum.” i) Find the equilibrium angle that the string makes with the vertical for a given speed v such that the ball traces a circle at uniform height. ii) Estimate...
The Seattle ferris wheel has a radius of 11-m and travels with an angular velocity of 1.5 rad/sec. What is the normal force (apparent weight) acting on a 57-kg person at the bottom of the swing?
What would be the tangential linear acceleration if an object's angular velocity was increased from 1 to 73 rad/s in 4s about a 5m radius of rotation (in m/s)?
1. Suppose a meter stick (length = 1 m) goes flying past you at velocity = 0.5c . As the stick goes by you measure its length. What length would you measure? (5 pts) 2. Suppose the Earth collapsed down to a black hole (this can’t really happen). What would be the radius of the black hole in meters? Newton’s gravitational constant G = 6.7 × 10-11 in metric units. The mass of the earth is 6.0 ×1024 kg. (5...
11. A 0.10 kg object with a velocity of 2.0 m/s in the +x direction makes a head-on elastic collision with a 0.15 k? object moving in the -x direction with a velocity of 3.0 s. What is the final velocity of the 0.10 kg object after the collision? A- 4.0 m/s
What is mass m?
