(a) Define SI unit of force. (b) Mention any two effects of force. (C) A body of mass 60 kg has a momentum of 300 kg `ms^(1)`. Calculate its velocity. (d) Why does a carpet beaten with a stick release dust?

Text Solution

Verified by Experts

(C )Here ,m=60 kg , p=300 kg `ms^(-1)` ,v=?
p=mv
`therefore 300=600xxv therefore xxv therefore v=(300)/(60)`
`therefore v=5 ms^(-1)`
