The correct answer is B. can you please help me answer my latest question too?
Answer:
The person has no displacement
Explanation:
The given parameters are
The location of the person = The equator
The distance covered in one revolution = Total distance around the body
The total distance around the Earth = The circumference of the Earth = 40.075 kilometres
The total distance moved by the person standing at the equator during the Earths complete revolution = 40,075 kilometres
The initial location of the person in relation to a fixed point in space outside Earth at the start of the revolution = x km
The final location of the person in relation to the fixed point in space outside Earth at the completion of the revolution = x km
The displacement = Change in position = Final location - Initial location
∴ The displacement = x km - x km = 0 km.
155 + 25 = 180 if that is what you are asking but 25 degrees is an acute angle
F=M*g
so M=F/g
M=190N/10m/s
m=19kg
Answer:
0 m/s
Explanation:
At the instant the ball reaches the top of its flight, it isn't moving up or down. So the vertical component of the instantaneous velocity is 0 m/s.
