At what angles should the nozzle point in order that the water land 2.0 m away
I don't even know where to start. Can anyone set me in the right direction?
Projectile motion is the motion of an object through the air or space under the influence of gravity. It is a combination of horizontal motion and vertical motion.
A fire hose exhibits projectile motion when the water is expelled from the nozzle. The water follows a parabolic path due to the force of gravity acting on it.
The factors that affect the projectile motion of a fire hose include the initial velocity of the water, the angle at which it is released, and air resistance.
To increase the range of a fire hose's water spray, the angle at which it is released should be increased. This will give the water a greater initial horizontal velocity, resulting in a longer range.
Yes, other factors such as wind can affect the projectile motion of a fire hose. Wind can alter the path of the water and change its range and direction. This is why firefighters must consider wind direction when using a fire hose.
