In the game of tetherball, a ball is hung from a vertical pole via a 0.75m rope. The rope is allowed to pivot freely from the top of the pole so the ball can swing around the pole. If the angle of the rope is 30° with respect to the pole, how much time does it take the ball to make one complete revolution around the pole?
A vial containing a blood sample is placed into a centrifuge, which spins the sample quickly to separate the blood into its parts. The centrifuge has a radius of 0.12 m, and spins at a rate of 1750 rpm. If the blood sample and vial have a combined mass of 95 g, what is the centripetal force holding the vial in place? 22.0 N 991 N 4030 N 383 N
Hi, today I had my engineering mechanics 1 test which I completely screwed up. I was quite confident in the uniform circular motion, but I had this problem in my exam which completely confused me. When I read "upward vertical acceleration" my head just start to spin as I couldn't understand what force could cause an upward acceleration. Could you help me with this problem? I bet it is easier than it looks, but still, I am confused about what is asking me and most importantly about the input it is giving me. I don't have my exam paper with me, but on my body diagram, I knew that on the aeroplane were exerted the Force of Contact Fn1 and the Force m1g in the y opposite direction. On the pilot was acting the Force of Contact with the seat of the aeroplane Fn2 and the m2g in the y opposite direction. Here is the problem: During an air show an aircraft comes out of a dive at the bottom of a circular arc at a horizontal speed of 97m/s. In the cockpit the aircraft pilot of mass 58kg…
A curve in a stretch of highway has radius 512 m. The road is unbanked. The coefficient of static friction between the tires and road is 0.700. What is the maximum safe speed that a car can travel around the curve without skidding?
A rubber ball is attached to a 1.44-meter string and spun in a horizontal circle. The tension in the string is 2.91 N. It takes 0.644 s for the ball to complete one revolution. Determine the mass (in kg) of the ball.
An accelerometer C is mounted to the side of the roller-coaster car and records a total acceleration of 3.3g as the empty car passes the bottommost position of the track as shown. If the speed of the car at this position is 195 km/h and is decreasing at the rate of 22 km/h every second, determine the radius of curvature p of the track at the position shown. Answer: p-i I ! m 0.73 m
A tennis ball connected to a string of radius 0.80 m is spun around in a vertical, circular path at a uniform speed of 2.5 m/s. When the ball is at the bottom of the circle, what is the magnitude of its acceleration? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
NASA uses a machine often called the "vomit comet" to mimic the effects of low gravity in space during astronaut training. The machine moves in circular arcs at a speed of v = 214 m/s. What is the radius the pilot must fly to create weightlessness as they go around the top of the circular arc? Give your answer in meters.
