Question

A ball of mass $m$ moves with speed $v$ and strike a wall having infinity mass amd it turns with same speed then the work done by the ball on the wall is then:

• A. $zero$
• B. $mv$ $J$
• C. $m/v.J$
• D. $v/m.J$

Answer 1

The correct option is A $zero$

Given that,

Mass $=m$

Speed $=v$

We know that,

$W=F\cos \theta \times s$

$W=F\cos \theta \times 0$

$W=0$

Hence, this is the required solution.
