10,000 units of momentum.
p=mv
20,000=m(2v)
10,000=mv
hi <3
the correct option would be A. displacement. displacement is distance in a direction
hope this helps :)
Answer:
i can't see the picture pls can you send a link or no
Explanation:
Answer:
acceleration, a = 9.8 m/s²
Explanation:
'A ball is dropped from the top of a building' indicates that the initial velocity of the ball is zero.
u = 0 m/s
After 2 seconds, velocity of the ball is 19.6 m/s.
t = 2s, v = 19.6 m/s
Using
v = u + at
19.6 = 0 + 2a
a = 9.8 m/s²
