F = m*a => a = F/m = 50N / 100 kg = 0.5 m/s^2
Vf^2 = vo^2 + 2gd
Vf^2 = 0 + 2*9.8m/s^2 *5.5m =107.8 m^2 / s^2
Vf = 10.4 m/s
Answer:
C. positron
Explanation:
Antimatter particles bind with each other to form antimatter, just as ordinary particles bind to form normal matter. For example, a positron (the antiparticle of the electron) and an antiproton (the antiparticle of the proton) can form an antihydrogen atom.
There you go.
Answer:
176.4 m
Explanation:
U = 0, t = 6s, g = 9.8 m/s^2
Use second equation of motion
H = ut + 1/2 gt^2
H = 0 + 0.5 × 9.8 × 6 × 6
H = 176.4 m
It is the displacement from the point of dropping of object.
Answer:
There must be a lot of dark matter that can be felt but not seen
