a 5kg mass resting on a smooth horizontal, frictionless table is connected to a cable which passes over a pulley and then is fastened to a hanging 10kg mass. find the acceleration of the two objects and the tension of the string.

Respuesta :

T= 5a

 -T +10g = 10a

-15a =10g

a=-10g/15

a= -1/2 g
Negative a means block is accelerating downwards.
