A wagon, initially traveling at a constant 8.5 m/s, starts going down a hill that creates an acceleration of 4.1 m/s2. How far downhill has the wagon gone after 2.7 s ?

Explanation:

Given parameters:

Initial velocity  = 8.5m/s

Acceleration  = 4.1m/s²

Time  = 2.7s

Unknown:

Distance downhill traveled  = ?

Solution:

To solve this problem, we have to adopt the right motion equation;

          S = ut + at²

where  s = distance

            u = initial velocity

            a = acceleration

            t = time taken

Insert the parameters and solve;

  S = (8.5 x 2.7) + ( x 4.1 x 2.7²)

  S = 22.95 + 14.95

  S = 37.9m

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.
