Question

HEY CAN ANYONE GUIDE ME IN SOLVING PHYSICS NUMERICALS OF THE FORMULA MV-MU T

Answer 1

There is another useage for the same eq...it proves newtons first law of motion on the basis of the second law.....from second law we can derive the eq F=ma or F=m(v-u)/t....or F=mv-mu /t....or Ft=mv-mu....now think about this; newtons first law states that an object continues to be in its initial state untill it is compelled to change that state by the application of an external force....or if there is no external force applied ( F=0 ) there is no change in its initial state ( either rest or motion) ...from the above eq ; if F=0 ; then we have 0=mv-mu or mv=mu or simply v=u! Which means that there is no change in its velocity; as explained by the first law!....cheers friend!
