When Fy is > the weight, the particle accelerates upward When Fy is < the weight, the particle does not accelerate Block S, mass M is sliding on a frictionless horizontal surface. Block H, mass m hangs from a massless, unstretchable cord wrapped over a massless pulley. Find expressions for the accelerations of the blocks and the tension in the cord.

Kukje cumminsThe heavier block in an Atwood machine has a mass twice that of the lighter one. The tension in the string is 16.0 N when the system is set into motion. Find the decrease in the gravitational potential energy during the first second after the system is released from rest.

V = V 1 +V 2 = √2Qq (D-d) / md D + √2Qq' / m D centimeters per second in which expression Q and q are in e.s. units, D and d in centimeters and m the mass of the particle in grams. But the calculation may be simplified, for if the charge is virtually constant through a great distance, the velocity finally attained will be:
