Answer:
no poop comes out from your but
Explanation:
travel through a vacuum at the speed of light. Other waves need a medium; sound waves need molecules that vibrate.
c .... work is force x distance as a definition
Explanation:
Momentum before = momentum after
m₁ u₁ + m₂ u₂ = m₁ v₁ + m₂ v₂
(65 kg) (0 m/s) + m (0 m/s) = (65 kg) (-3.5 m/s) + m (4 m/s)
m ≈ 57 kg
To calculate instantaneous speed, we need to divide part of the total distance traveled by time. However, we don't want to use the distance of the entire trip, because that will give us average speed.
