She was involved in energy conversions in the lab. She often transformed chemical energy to
heat energy and then to mechanical energy,
but she wouldn’t tell anyone about it. Who
was she?

Awheel rotates without friction about a stationary horizontal axis at the center of the wheel. a constant tangential force equal to 82.0 n is applied to the rim of the wheel. the wheel has radius 0.150 m . starting from rest, the wheel has an angular speed of 12.8 rev/s after 3.88 s. what is the moment of inertia of the wheel?

Awave is produced in a rope. the wave has a speed of 33 m/s and a frequency of 22 hz.

Acar traveling at 22 m/s starts to decelerate steadily. it comes to a complete stop in 15 seconds. what is it’s acceleration?
