Starting from rest, a soapbox derby team accelerates down a hill in 15 seconds. What is the final velocity (in m/s) at the bottom of the hill? *The Soapbox Derby hill has an overall length (displacement) of 105 meters

Light from the sun reaches the earth in 8.3 minutes. the velocity is 3.00 x 10^8 m/s. how far is earth from the sun? i know how to get to d = (3 x 10^8 m/s)(498 sec). i just don't know how to get from there to the answer being 1.5 x 10^11 m.

The slope of a velocity time graph over any interval of time gives the during that interval

Convection occurs when thermal energy is transferred by the movement of
