A cord is used to vertically lower an initially stationary block of mass m kg at a constant downward acceleration of g/4. the bl
Natali5045456 [20]

(a) We know that work is the product of Force and Distance so: (in this case Distance is negative since going down so –d)

work = force * distance

work = M * (g - g/4) * -d

work = -3Mgd/4 <span>

(b) The work by the weight of the block is simply:</span>

work = Mgd <span>

(c) The kinetic energy is simply equivalent to the net work, therefore:</span>

KE = net work

KE = Mgd/4 <span>

(d) The velocity is:</span>

v = √(2*KE/M)

Plugging in the value of KE from c:

v = √(2*Mgd / 4M)

<span>v = √(gd / 2) </span>
