Every unit on the map equals 25000 of the unit in real life.
Answer:
<u>Velocity's direction will be in opposite to direction of ball.</u>
Explanation:
Momentum = 8m/s,
using law of conservation of momentum;
50v + 20 = 0 (as initial momentum is zero)
or
p = m/v (m is mass and v is velocity)
v = p/m (p is momentum)
putting values;
v = 20/50
= 0.4 m/s
it proves that direction of velocity is opposite direction of ball.
My guess is tank B because the pieces are smaller. I assume they will dissolve faster.
Hope this helps!
Vf^2 = Vi^2 + 2ad
Vf^ = 0 + 2(-9.8)(-12)
Vf^2 = 235.2
Vf = 15.3 m/s
The correct answer is b) 15 m/s
