Two forces P and Q act on an object of mass 8.00 kg with Q being the larger of the two forces. When both forces are directed to the left, the magnitude of the acceleration of the object is 1.30 m/s. However, when the force P is directed to the left and the force Q is directed to the right, the object has an acceleration of 0.600 m/s to the right. Find the magnitudes of the two forces P and Q Did you consider the sign of the forces for the two cases given here? N Enter a number er the sign of the forces for the two cases given here? N Need Help? Read It

Explanation / Answer

when both are directed towards left

Fnet = lQl + lPl = m*a1 .......(1)

when P is directed towards left and Q towards right

Fnet = lQl - lPl = m*a2.........(2)

1 + 2

2*lQl = m*(a1+a2)

lQl = m*(a1+a2)/2

lQl = 8*(1.3+0.6)/2

magnitude of Q = 7.6 N

from 1

lpl = m*a1 - lQ1l

lpl = (8*1.3) - 7.6

magnitude of P = 2.8 N
