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).
Explanation:
If a body does not cover a equal distance at a equal interval of time it is said to be non uniform motion...
Answer:
Explanation:
Given
Magnitude of charge is
Force experienced is
Electric field intensity is the electrostatic force per unit charge
Thus, the electric field intensity is
