Question

determine the acceleration for a jet taking off on a run way as it starts from rest and reaches a velocity of 50m/s over a period of 10s

Answer 1

since v increased by 50m/s in 10s, that would be 50m/s / 10s = 5m/s^2 acceleration

Answer 2

im and Rick both can run at speed vr and walk at speed vw, with vr>vw. They set off together on a journey of distance D. Rick walks half of the distance and runs the other half. Tim walks half of the time and runs the other half
