Most Important Selected Qs for JEE AdvancedPhysicsMotion in One Dimension
Two boys are standing at the points A and B on the ground, where A B=a . The boy at B starts running in a direction perpendicular to A B with velocity v₁ . The boy at A starts running simultaneously with velocity v and catches the other in time t then t is
Options
- Aa v^2+v₁^2
- Ba v+v₁
- Ca v-v₁
- Da v^2-v₁^2
Correct answer
D. a v^2-v₁^2
Step-by-step solution
aligned & a ^2+ v ₁^2 t ^2= v ^2 t ^2 & t = a v ^2- v ₁^2 aligned
