A) distance covered by the body is \[u+F/2\]
B) momentum of the body increases by F
C) final velocity of the body is \[u\text{ }+\text{ }F\]
D) all of these
Correct Answer: D
Solution :
[d] Change in momentum \[=F(t)=F(t=1s)\] Since mass of the body is 1 kg, hence change in velocity is also F or the final velocity of the body will be \[u+F\]. Acceleration, \[a=\frac{F}{m}=F\] \[{{a}_{x}}\] \[S=ut+\frac{1}{2}a{{t}^{2}}=u+\frac{1}{2}F\] \[(t=1s)\]
