Answer:
3504.4 kgm/s
Explanation:
First, convert km/hr to m/s:
19 km/hr x 1000m/1km x 1/60min x 1/60s = 5.28 m/s
p = mv
p = (664 kg)(5.28 m/s) = 3504.4 kgm/s

If there are no windows, then the illumination in the room depends
only on the room and what's in it, not on anything outside.
The time of day has no effect. The other things all do.
Answer:
∆ = 14°
Explanation:
Let the angle be ∆
Opposite = 2.07 m/s
Adjacent = 8.3 m/s
Tan ∆ = opposite / adjacent
Tan ∆ = 2.07 / 8.3
Tan ∆ = 0.2494
∆ = ArcTan (0.2494)
∆ = 14°
The angle from vertical the raindrops make for a person jogging is 14°
If there is no friction, the roller coaster would keep moving forever but a constant velocity. The only way it would accelerate is if there was a force continually pushing on it.
