What is the speed of a car that travels 0.200 km in 95 seconds? State your answer in meters per second.
WARRIOR [948]

Answer:

<h2>2.10 meters per second</h2><h2 />

Explanation:

speed (velocity) = distance / time

                          = <u>0.2 km (1000 m/km) </u>

                                     95 secs.

                          = 2.10 meters per second

Derive a general formula for projectile motion with the object launched at an angle
vagabundo [1.1K]

Answer:

  y = x tan θ - (g / 2v₀² cos² θ) x²

Explanation:

An equation is called a general formula that relates the position on the x-axis and the height on the body's axis.

Let's write the position on each axis

X axis. No acceleration

         x = v₀ₓ t

Y Axis.  There is the acceleration of gravity

        y = v_{oy} t - ½ g t²

Let's clear the time in the first equation and substitute in the second

       y = v₀ sin θ  (x / v₀ₓ) - ½ g (x / v₀ₓ)²

       y = v₀ sin θ / v₀ cos θ x - ½ g x² / v₀² cos² θ

       y = x tan θ - (g / 2v₀² cos² θ) x²

This is the trajectory equation in projectile launching
