A particle is moving in a circle of radius R. At t = 0, it is located on the x-axis. The angle the particle makes with the positive x -axis is given by 0 = At² + Bt³ What is the magnitude of the tangential acceleration, atan of the particle at a time t > 0? Express your answer in terms of R, t, A, and B as needed. What is the magnitude of the radial acceleration, larad of the particle at a time t > 0? Express your answer in terms of R, t, A, and B as needed.

A model of a helicopter rotor has four blades, each of length 3.4 mm from the central shaft to the blade tip. The model is rotated in a wind tunnel at a rotational speed of 500 rev/minrev/min. 1. What is the linear speed of the blade tip? Express your answer in meters per second. 2. What is the radial acceleration of the blade tip expressed as a multiple of the acceleration due to gravity, gg? Express your answer as a multiple of gg. 3.

A disk spins at 4.0 revolutions/second. What is its period, in second? 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.

A runner runs around a circular track. He completes one lap at a time if t=497s at a constant speed of v=3.9m/s. What is the radius r in meters of the track?what was the runners centripetal acceleration ac in m/s^2 during the run?

A centrifuge in a biochemistry laboratory rotates at an angular speed of 3,650 rev/min, clockwise (when viewed from above). When switched off, it rotates through 48.0 revolutions before coming to rest. Assuming it is constant, what is the magnitude of angular acceleration (in rad/s²)? rad/s² What is the direction of the angular acceleration (again, when viewed from above)? clockwise оо counterclockwise The magnitude is zero.

1. A stopwatch starts while race car travels at 13 m/s from the pit area and accelerates at a uniform rate to a speed of 37 m/s in 5 s moving on a circular track of radius 548 m. Assuming constant tangential acceleration, find (a) the tangential acceleration, and (b) the radial acceleration,at the instant when the speed is v=7 Once you have both of those…. find the magnitude of a at any moment a= 2. A stopwatch starts while race car travels at 5 m/s from the pit area and accelerates at a uniform rate to a speed of 23 m/s in 16 s moving on a circular track of radius 466 m. Assuming constant tangential acceleration, find (a) the tangential acceleration, and (b) the radial acceleration,at the instant when the speed is v=15 Once you have both of those …. find the magnitude of a at any moment a= 3. A stopwatch starts while race car travels at 7.0 m/s from the pit area and accelerates at a uniform rate to a speed of 22 m/s in 3 s moving on a circular track of radius 491 m. Assuming constant…
