A block of wood of mass 5kg is pulled on a platform by a force of 40N as illustrated in the diagram above. If the frictional force, F experienced by the block is 12N, calculate the magnitude of the acceleration of the acceleration of the block
2.4ms-2
5.6ms-2
8.0ms-2
2.4ms2
Correct answer is B
F + Ma = P
a = P−Fm
= 40−125=5.6ms−2
