How much momentum will a dumb-bell of mass

$10\ kg$ transfer to the floor if it falls from a height of

$80\ cm$ ? Take its downward acceleration to be

$10\ m\ s^{–2}$

From the Equation of motion -

$III$ , We know that,

$i^{i} - i^{i} = i \times i \times i$

We know that the formula to calculate the momentum of the object,

Momentum $=$

$kg\ m\ s^{-1}$
