Aferris wheel with a 15-m radius makes three complete revolutions in one minute about its horizontal axis. what is the magnitude and direction of a passengers acceleration at the lowest point during the ride?

, upward

Explanation:

The passenger on the wheel experiences a centripetal acceleration, which is the one that keeps him in a circular motion.

The direction of this acceleration is always towards the centre of the circular trajectory: so when the passenger is at the lowest point of the ride, the acceleration is upward.

Concerning the magnitude, it is given by

where

is the angular velocity

r = 15 m is the radius

We need to find the angular velocity; we know that the wheel completes 3 revolutions in one minute. Each revolution corresponds to an angle of rad, so the total angular displacement is

rad

And the time is

So the angular velocity is

And substituting into the equation of the acceleration,

answer; the correct answer is technician a; ///100%good luck

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.
