Question

Calculate the acceleration of the body of mass 3 kg on which a force of 42N has been applied for 5s.

Answer 1

Heya mate....  Force=42N Mass=3kg  As we know that...force=mass × acceleration  And acceleration= final velocity-initial velocity÷time taken  Here.. a=v-u÷5 U=o[because starts from rest] A=v÷5  A=42N÷3kg A=14m sec^-2  14=v÷5 V=70m sec^-1  Hope it helps u  @skb
