That depends on how far it is from the nearest planet. If it's on the surface of Earth, it weighs (19 kg) x (9.8 m/s^2) = 186.2 newtons.
Explanation:
h=((usinx)^2)/2g
12.7=((usin(19))^2)/(2×9.8)
(12.7×2×9.8)=(usin(19))^2
248.92=(usin(19))^2
usin19 =√248.92 =15.78
U =15.78/(sin19)
=48.46m/s----> speed
Explanation:
1 mega Hertz = 1000000 hertz
Answer:
A.
Explanation:
The normal force is always perpendicular to the surface of contact, her weight is always pointing straight down (or towards the center of Earth), and the friction opposes the direction of her motion. Free body diagram A. is the only one that fits properly displays those 3 things.
