Answer 1

Explanation:

Answer:

Distance covered in first 2 seconds = 10 m,

Distance covered in first 2 seconds = 10 m,Body is in rest between 2 to 6 seconds so distance = 0 m,

Distance covered in first 2 seconds = 10 m,Body is in rest between 2 to 6 seconds so distance = 0 m,Distance covered in first 6 to 8 Seconds = 10 m,

= 10 m,Distance covered in first 8 to 10 seconds = 10 m,

= 10 m,Distance covered in first 8 to 10 seconds = 10 m,Distance covered in first 10 to 12 seconds = 10 m,

= 10 m,Distance covered in first 8 to 10 seconds = 10 m,Distance covered in first 10 to 12 seconds = 10 m,So final distance = 10+10+10+10= 40 m.

= 10 m,Distance covered in first 8 to 10 seconds = 10 m,Distance covered in first 10 to 12 seconds = 10 m,So final distance = 10+10+10+10= 40 m. Body is start at 0 seconds and comes to same position at 12th seconds so displacement is zero.

= 10 m,Distance covered in first 8 to 10 seconds = 10 m,Distance covered in first 10 to 12 seconds = 10 m,So final distance = 10+10+10+10= 40 m. Body is start at 0 seconds and comes to same position at 12th seconds so displacement is zero.⇒ Distance = 40 m, Displacement = 0
