A0.140 kg baseball is thrown horizontally with a velocity of 28.9 m/s. it is struck with a constant horizontal force that lasts for 1.85 ms, which results in a velocity of 37.0 m/s in the opposite direction. what was the magnitude of the horizontal force?
a) 0.613 kn
b) 2.19 kn
c) 2.80 kn
d) 4.99 kn

Explanation:

Force = Mass x Acceleration

F = ma

m = 0.14 kg

We have equation of motion v = u + at

     Initial velocity, u = 28.9 m/s

     Final velocity, v = -37 m/s    

     Time, t = 1.85 ms = 0.00185 s

     Substituting

                      v = u + at  

                      -37 = 28.9 + a x  0.00185

                      a = -35621.62 m/s²

    Acceleration, a = -35621.62 m/s²

F = ma = 0.14 x -35621.62 = -4.99 kN

Option D is the correct answer.

magnityde and direction

depends on what you mean by "group." for order, it would be coleoptera (beetles). for class, it would be insecta (insects). for phylum, it would be the arthropoda (animals with jointed exoskeletons).
