Question on: WAEC Physics - 2013
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
A
2.4ms-2
B
5.6ms-2
C
8.0ms-2
D
2.4ms-2
Ask EduPadi AI for a detailed answer
Correct Option: B
F + Ma = P
a = (\frac{P - F}{m})
= (\frac{40 - 12}{5} = 5.6ms^{-2})
