1). trajectory
2). person sitting in a chair
3). 490 meters
4). 65 m/s
5). False. The projectile's displacement, velocity, and acceleration have vertical and horizontal components, but the projectile doesn't.
6). False
7). The vertical component of a projectile doesn't change due to gravity, but the vertical components of its displacement, velocity, and acceleration do.
The vertical components do NOT equal the horizontal components.
8). Decreasing if you include the effects of air resistance. Constant if you don't. Gravity has no effect on horizontal velocity.
9). We can't see the simulation. But if the projectile doesn't have jets on it, then as it travels upward, its vertical velocity must decrease, because gravity is trying to not let it get away.
10). We can't see the simulation. But if the projectile is traveling downward, we would call that "falling", and its vertical velocity must increase, because gravity is pulling it downward.

Answer:
19620 Watt = 19.62 kWatt
Explanation:
Power output (P) is work (W) divided by time (t): P = W/t
A work (W) is a product of a force (F) and a distance (d): W = F · d
Since the force is a product of mass and acceleration: F = m · a
then work would be: W = m · a · h
P = W/t
W = m · a · h
P = m · a · h / t
We have:
P = ?
m = 1000 kg
a = 9.81 m/s² (gravitational acceleration on the Earth)
h = 10 m
t = 5s
P = m · a · h / t = 1000 kg · 9.81 m/s² · 10 m / 5 s = 19620 Watt = 19.62 kWatt
