Question

solve this question ⁉️​

Answer 1

acceleration of block = 10 m/s^2

FOR A , work done = 100*500 J

= 50000 J

FOR B , distance covered by B in 10 sec = 100 m

so, relative distance travelled by block = 400 m

work done = 100*400 = 40000

FOR C , distance covered by C in 10 sec = 500

bcoz there is no net relative acceleration of block so, work done w.r.t is zero

HOPE IT HELPS UH.........
