How is Newton’s first law demonstrated by your zip line

Nikitich [7]

Newton's First Law: An object in motion stays in motion, an object at rest stays at rest unless an unbalanced force acts upon it. For example, when zipping down the zip line you will stay in motion unless an outside force interferes. ... The more mass the more force needed.

A toy car is placed 29.0cm from a convex mirror. The image of the car is upright and one-sixth as large as the actual car. Calcu

borishaifa [10]

Answer:

The power of the mirror is -17.24 diopter.

Explanation:

Magnification of an image,m = $\frac{1}{6}$

Distance of the object from the mirror = u = 29.0 cm

Distance of an image from the mirror = v

Magnification = $m=\frac{-v}{u}$

$\frac{1}{6}=\frac{-v}{u}$

$v=\frac{-u}{6}$

$\frac{1}{f}=\frac{1}{u}+\frac{1}{v}$

$\frac{1}{f}=\frac{1}{u}+\frac{-6}{u}$

$f=\frac{-u}{5}=\frac{-29.0 cm}{5}=-5.8 cm$

Focal length of mirror = -5.8 cm =-0.058 m

Power of the lens = P

$P =\frac{1}{f}$

$P=\frac{1}{-0.058 m}=-17.24 D$
