A flywheel with a radius of 0.230 m starts from rest and accelerates with a constant angular acceleration of 0.670 rad/s2 Part A Compute the magnitude of the tangential acceleration, the radial acceleration, and the resultant acceleration of a point on its rim at the start. Enter your answers separated with commas. ΤΙ ΑΣφ ? Atan, Arad, Atotal = m/s...
A uniform rigid disc is rotating around its center of mass. (a) Is it possible for the disc to have a centripetal acceleration but no tangential acceleration (that is, aT = 0). (b) If yes, provide an example. (c) Is it possible for the disc to have a tangential acceleration but no centripetal acceleration (that is aC = 0). (d)...
Astronauts often have to train in high-g (high gravity) environments before they embark on space missions. A space-training module consists of a capsule that rotates insides a horizontal circular track of radius 115 m. The rotational speed increases at a constant rate from rest such that the capsule finishes its first cycle in 8.00 s (a) How long does it...
(a) What is the tangential acceleration of a bug on the rim of a 9.0 in diameter disk if the disk moves from rest to an angular speed of 79 rev/min in 3.0 s? Your response differs from the correct answer by more than 10%. Double check your calculations. m/s2 (b) When the disk is at its final speed, what...
To throw the discus, the thrower holds it with a fully outstretched arm. Starting from rest, he begins to turn with a constant angular acceleration, releasing the discus after making one complete revolution. The diameter of the circle in which the discus moves is about 1.7 m . Part A If the thrower takes 0.90 s to complete one revolution,...
(10 pts) A car races around a circular track with a radius of 500 m. The cars mass is 750 kg and it takes 10 minutes to make one complete lap. Calculate the tangential velocity, centripetal acceleration, and centripetal force.
A test car starts from rest on a horizontal circular track of 80 m radius and increase its speed at a uniform rate to reach 100 Km/h in 10 seconds. Determine the magnitude of total acceleration of the car 8 seconds after the start . Rotation of the radially slotted arm is governed by 0-0.21 + 0.02r, where 0 is...
An ultracentrifuge accelerates from rest to 90900 rpm in 1.95 min. Randomized Variablesf = 90900 rpm t = 1.95 min l = 9.1 cm Part (a) What is its angular acceleration in rad/s2? Part (b) What is the tangential acceleration of a point 9.1 cm from the axis of rotation in m/s2? Part (c) What is the centripetal acceleration in...
A 0.25 kg ball is attached to a string. The ball goes around in a circle that is horizontal (parallel) to the ground. The circular path has a radius of 1.5 m. The rotation is at a constant rate of 50 rpm. a) list the given b) what is the tangential velocity of the ball? c) what is the centripetal...
The direction of the centripetal force is always in the same direction a. as the centripetal acceleration vector b. as the velocity vector c. that an object would have if the centripetal acceleration suddenly stopped d. as the direction of motion of the object In this question, "constant in direction" refers to a fixed direction such as east or west....
