2. A stone is thrown vertically upward with a speed of 22m/s.

Eduardwww [97]

Answer:

Explanation:

Energy E is conserved:

$E=\frac{1}{2}mv^2+mgh$

If v₀ = 22m/s, h₀=0m and h₁=25m:

$E=\frac{1}{2}mv_0^2=\frac{1}{2}mv_1^2+mgh_1$

Solving for v₁:

$v_1=\sqrt{v_0^2-2gh_1}$

There is no real solution, because the stone never reaches 25m.

How is the acceleration of a car traveling on an elevated air track related to the angle of elevation and the height of elevatio

vitfil [10]

on a given inclined we know that net force is given by

$F_{net} = - mgsin\theta$

here we know that

$F_{net} = ma$

so here we have

$ma = - mg sin\theta$

$a = - gsin\theta$

so here acceleration depends directly on angle of inclination

now we also know that if height of the inclined is H and its length is L

then we can write

$sin\theta = \frac{H}{L}$

so the acceleration is given as

$a = - g*\frac{H}{L}$

so acceleration also depends directly on height of the inclined plane
