Calculate the average speed of spacecraft orbiting mars

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

Awind turbine is rotating counterclockwise at 0.5 rev/s and slows to a stop in 10 s. its blades are 20 m in length. (a) what is the angular acceleration of the turbine? (b) what is the centripetal acceleration of the tip of the blades at t=0s? (c) what is the magnitude and direction of the total linear acceleration of the tip of the blades at t=0s?

Acalorimeter uses the principle that thermal energy flows from hotter material to colder material until both reach the same
