An ultracentrifuge accelerates from rest to 9.93 x 105 rpm in 2.23 min. What is its angular acceleration in radians per second squared? angular acceleration: What is the tangential acceleration of a point 9.30 cm from the axis of rotation? tangential acceleration: radial acceleration: rad/s² What is the radial acceleration in meters per second squared and in multiples of g of this point at full revolutions per minute? radial acceleration in multiples of g: m/s² m/s²

Question 6: A particle is moving in a circular path of radius R. At some in- stant, its acceleration a makes angle 0 with the horizontal as shown in Figure 2. At that instant, what is the speed of the particle? Figure 2 Select one: VaR cos 0 VaRtan 0 VaRsin 0 aR cot 0 aRsin? 0

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.

can i have some help with this problem:

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?

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…

A jet fighter pilot flying at 300 m/s makes a turn with a radius of 1.5 km. Determine the radial acceleration in g’s experienced by the pilot due to the turn.Also Determine the tangential and total linear acceleration.

An object moving in a circle with a radius of 0.5 meters accelerates tangentially at 5 meters per second squared. At the instant, the object’s net acceleration is 9 meters per second squared, determine its speed.

A motorcycle, starting from rest, accelerates at 2.82m/s2m/s2 on a circular track with a 205mm diameter.  What is the elapsed time, in seconds, at which the centripetal acceleration of the motorcycle has the same magnitude as its tangential acceleration?

A ball tied to the end of a cable is spun ina circle with a radius 0.32 m making 3 revolutions every 7.2 seconds. What is the magnitude of the acceleration, a (in m/s ), of the ball? Give your answer accurate to one decimal place and enter only the number (and not the unit) below: a = Type your answer.
