Answer 1

A car accelerates from 13m/s to 25m/s in 6.0s. What was its acceleration?

How far did it travel in this time?

Assume constant acceleration.

:

 

a = %2825+-+13%29%2F6 = 12%2F6 = 2 m/s^2

:

Av speed: %2825%2B13%29%2F2 = 38%2F2 = 19 m/sec

:

Dist = speed * time

19 * 6 = 114 meters

Answer 2

hop you get it......
