A. as particle A is constantly moving at uniform velocity and also at equal time interval so, it is undergoing uniform motion but particle B is not going at uniform velocity but uniform acceleration of 10m/s so, it is non-uniform motion but uniform acceleration.
B. Displacement by B in four second-ut+½at²
=0*4+½*10*4² m
=0+5*16 m
=80m
Displacement by A in four second= ut+½at²
= 30*4+½*0*4² m
= 120 m
Difference of the bodies after 4 sec= (120-80)m
=40m
