I believe Isaac Newtons Law " Gravity ".
Answer:
v = 1 m/s
Explanation:
from the principle of conservation of momentum, we have following relation
initial momentum = final momentum
where
m1 = 1.14 kg
v1 = 2.0 m/s
m2 = 1.14 kg
v2 = 0 m/s
putting all value in the above equation
v = 1 m/s
Answer:
1) distance walked = 210 m
2) not sure
3) avg speed = total d/ total t = 210/52 = 4 m/s approx
4) For avg vel, use the formula - displacement/time
Explanation:
im not fully sure but i studied this last year
Answer:-4
Explanation:because
10protone +10
14 electrone-14
5 neutrones0 the result will be
10-14=-4
Answer:
M V = m v conservation of momentum (Caps-cannon Small-projectile)
V = m / M * V = 2 / 2000 * 200 m/s = .2 m/s recoil velocity of cannon
KE = 1/2 M V^2 = 2000 / 2 kg * (.2 m/s)^2 = 40 kg m^2/s^2 = 40 J
