Two iron balls of masses W1 = 5.7kg and W2 = 7.6kg are connected by a string on a frictionless table. At a specific distance, when W2 has an acceleration a2 = 3.6 m/s2
(a) what is the force on W2 and
(b) what is the acceleration of W1?
Force acting on the iron ball is equal to its products of mass and acceleration that is
For question a to find the force on W2, we will use the above formula.
Mass of the iron ball m = 7.6kg
Acceleration of the iron ball ,
Force F on iron ball = ma
Now to find the acceleration of W1 we need to get force and the only force that is acting on W1 is the force of W2.
Mass of the iron ball m = 5.7kg
Acceleration of the iron ball a =?
Force on iron ball F = -27.36N
