Answer:
by Multiply Force,change direction and speed multiply
No becuase the simplified case of constant speed, use the formula:
<span>distance = speed x time</span>
Answer:
10.347 minutes.
Explanation:
According to F = ma, she exerts force on camera of the magnitude
F = 0.67Kg*12m/
= 8.04N, assuming it took her one second to accelerate camera to 12m/s, then by newtons third law, which says every action has equal and opposite reaction , the camera exerts the same amount of force on the astronaut which gives her acceleration of a =
.
and velocity of V = 0.1130801680m/s.
at this velocity , the astronaut has to cover the distance of 70.2 meters, it will take her 620.7985075s = 10.347 min to get to the shuttle (using S = vt).
C) The longer the line, the greater the magnitude of the vector. As for the direction, just think of a compass.
Answer:
i think its the third one or second one
