Q1 the two rotating systems shown in the figure differ only, Ask an Expert

Academics

Q1. The two rotating systems shown in the figure differ only in that two identical movable masses are positioned at different distances from axis of rotation. If you release the hanging blocks at the same time from rest, and if the ropes do not slip, which block lands first?

Q2. After being accelerated to a speed of 1.8×10^5 m/s , particle enters a uniform magnetic field of strength 0.800 T and travels in a circle of radius 30.0 cm (determined by observing where it hits the screen). The results of this experiment allow one to find m/q.

Q3. Susie (of mass 86 kg) is rollerblading down the sidewalk going 32 miles per hour. She notices a group of workers down the walkway who have suddenly blocked her path, and she makes a quick stop in 1.8 seconds. What is Suzies average acceleration?
