- A 0.040 kg ball tied to a string moves in a circle that has a radius of 0.700 m. If the ball is accelerating at 43.2 m/s2, what is the tangential velocity of the ball?NASA is planning a space station that will have artificial gravity. The plan is for a 250 m radius. NASA wants the acceleration at the outer edge to be 4.9 m/s2. Calculate the velocity of the station’s rotation. The station will be equipped with a launcher at the end of each spoke. Choose the diagram that shows the direction a small spaceship will go when it is released from the station, and note how fast it will go.A child is holding a string with a ball tied at the end. The child spins around in a circle causing the ball to travel in uniform circular motion. While doing this, the 1.3 m long string makes a 48.8◦ angle below horizontal. What is the tangential speed of the ball?
- George swings a ball around him, in uniform circular motion. The circle's radius is r. George inadvertently releases the string, and the ball goes outward. He catches the string again, and now the ball goes around him at a new rotation rate, with a new radius r + Δr. Calculate the new rotation rate (in rev/s). r = 2.6 m Δr = 0.5 m Original rotation rate = ωi = 1.6 rev/s The ball's mass is m = 83 gramsAn audio compact disk (CD) player is rotating at an angular velocity of 32.5 radians per second when playing a track at a radius of 4.0 cm.

The merry-go-round accelerates from rest up to 0.40 rev/s in 10 s. a. What is the angular acceleration of the merry-go-round? Express this in radians/second. b. What is the angular velocity at 5 s? c. Calculate the centripetal acceleration and tangential acceleration at 5 s. d. What is the total acceleration at 5 s? e. If the coefficient of static friction between the child and the surface of the merry-go-round is 0.6, does the child fall off before 5 s? Hint: To determine this, calculate the frictional force and force due to the acceleration of the merry-go-round on the child. Compare the two forces to find which is larger than the other, therefore overcomes the other.Please help solve for Fn
