Question:

Two blocks of mass m and 3msuspended from a pully which is fixed.find the acceleration of mass 3m.

Hotu G.

Using Newtonian mechanics acceleration for both blocks will be same so acceleration =net force/total mass a=(3mg-mg)/(4m) =g/2 meter squre /second square

Question:

The pressure of water in a water pipe when a tap is opened and closed is respectively 3xpower(10,5)N/meter square and 3.5xpower(10,5)N/meter square.find out the velocity when a tap is opened.

Hotu G.

Using Bernoulli theorem : pressure due to atmosphere +pressure due to velocity =pressure (closed tap) by calculation v=10m/s
