Answer:
Step-by-step explanation:
1). Distance traveled during the first minute (A-B)
= Distance from A to C + Distance from C to D + Distance from D to B
= 40 + 100 + 40
= 180 m
Option (4) will be the answer.
2). Displacement after first minute (A-B)
= Distance from A to B
= 180 m East
Option (2) is the answer.
3). Distance traveled during the first 2 minutes (A - B - C)
= Distance from A to B + Distance from B to C
= 180 + 140
= 320 m
Option (3) will be the answer.
4). Displacement after first 2 minutes (A-B-C)
= Distance between A and C
= 40 m towards east
Option (1) is the answer.
5). Distance traveled during 3 minutes (A-B-C-D)
= Distance between A to B + Distance between B to C + Distance between C to D
= 180 + 140 + 100
= 420 m
Option (4) is the answer.
6). Displacement after total 3 minutes (A-B-C-D)
= Distance between A and D
= Distance between A to C + distance between C to D
= 40 + 100
= 140 m
And the direction is towards East.
Option (3) is the answer.
