A man A moves with constant velocity `3m/sec` along the x-axis. Another man B moves towards A After how much time will B meet A. if B moves with a constant speed of `4 m/sec`. Distance of A to B is 50m.

When two particeles A and B are at point O, A is moving with a constant velocity 50 m/s , whle B is not moving. But B possesses a constant acceleration of 10 m/ s^(2) . After how much time they will be at a distance of 125 m ?

Car A starts from a point O and moves with constant velocity 9 m//s . After 2 s , another car B begins its journey from O and follows car A . If car B starts from rest and moves under constant acceleration 4 m//s^(2) , after how much time and at what distance from O the cars meet?

A proton moves at a constant velocity of 50 m/s along the x-axis, in uniform electric and magnetic fields. The magnetic field is B = (2.0 mT)hatj . What is the electric field?

A particle 'A' starts moving frorri point A with constant velocity 4 m/s along x-axis. Another particle 'B' initially at rest starts moving along x-axis after (8/3), sec after the start of A, with acceleration varying a=4=(3-t) m//s^(2) Variation of velocity uf the particle B with time is best represented by :
