363566 At any instant the velocity of a particle of mass \(500\;g\) is \(\left(2 t \hat{i}+3 t^{2} \hat{j}\right) m s^{-1}\). If the force acting on the particle at \(t=1 s\) is \((\hat{i}+x \hat{j}) N\), then the value of \(x\) will be

363567 A body of mass '\(m\)' is traveling with a velocity '\(u\)'. When a constant retarding force '\(F\)' is applied, it comes to rest after travelling a distance \('{s_1}'\). If the initial velocity is '2\(u\)', with the same force '\(F\)', the distance traveled before it comes to rest \('{s_2}'\). Then

363568 Assertion :
If the net external force on the body is zero, then its acceleration is zero.
Reason :
Acceleration does not depend on force.
