Answer A sounds about right
Multiplied by; speed = distance x time
Answer:
11 m/s south
Explanation:
The velocity of the passenger relative to the river bank is equal to the velocity of the passenger relative to the ferry, plus the velocity of the ferry relative to the river, plus the velocity of the river relative to the river bank.
v_passenger,bank = v_passenger,ferry + v_ferry,river + v_river,bank
If we take north to be positive and south to be negative:
v = 1.0 m/s + (-10 m/s) + (-2 m/s)
v = -11 m/s
v = 11 m/s south
Answer:
second lag
Explanation:
If in a cup game, a specified time limit is assigned to both teams to score high. If both teams are unable to score or if score of both the teams is equal then there is another second lag played where each team tries to score high. Even if in second lag both teams fail to score higher than other the last third lag is played or else game is declared draw.
<u>Answer:</u>
Resultant displacement is 4 km north.
<u>Explanation:</u>
Let east represents positive x- axis and north represent positive y - axis. Horizontal component is i and vertical component is j.
A runner traveled 15 kilometers north then backtracked 11 kilometers south before stopping,
So initial displacement, 15 kilometers north = 15 j km
Second displacement, 11 kilometers south = -11 j km
Total displacement = 15 j -11 j = 4 j km
Total displacement is 4 km north.
