Question

20 kg wooden block is pushed from the rest to your final velocity of 10 metre per second into second the black Travels a distance of 6 metres how much work was done in the pushing book

Answer 1

Answer:

720 Nm

Explanation:

d = 6 m                              a = v / t                            F = m.d

m = 20 kg                          a = 10 / d/s                      F = 20 . 6

v = 10 m/s                           a = 10 / 6/10                    F = 120 N

a = 16.67 m/s^2                  a = 10 / 0.6

F =                                      a = 16.67 m/s^2

Work done = F . d

                   = 120 . 6

                   = 720 Nm
