Can someone me! a sprinter starts from rest, and accelerates at 1.87 m/s^2 over a distance of 14.0 m. what is her final velocity?

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

In a good thermo flask the main cause of heat loss is

The bar of prob. 5/82 is repeated here. the ends of the 0.4-m bar remain in contact with their re- spective support surfaces. end b has a velocity of 0.5 m/s and an acceleration of 0.3 m/s2 in the di- rections shown. determine the angular accelera- tion of the bar and the acceleration of end a.
