Example 4.6 provides a nice example of the overlap between kinematics and dynamics. it is known that the plane accelerates from rest to a take-off speed of 70 m/s over a distance of 940 m. use of the kinematic equation (vx)2f=(vx)2i+2axδx to find the acceleration of the plane, and then answer the following question. how long does it take the plane to reach its take-off speed?

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.
