A small candle is 38 cm from a concave mirror having a radius of curvature of 24 cm. (a) what is the focal length of the mirror?
Finger [1]
For a concave mirror, the radius of curvature is twice the focal length of the mirror:
r=2f
where f, for a concave mirror, is taken to be positive.

Re-arranging the formula we get:
f= \frac{r}{2}
and since the radius of curvature of the mirror in the problem is 24 cm, the focal length is
f= \frac{24 cm}{2} = 12 cm

A 1055-kg van, stopped at a traffic light, is hit directly in the rear by a 660-kg car traveling with a velocity of 2.00 m/s. As
frosja888 [35]

Answer:

<h3>0.77m/s</h3>

Explanation:

According to law of conservation of energy

m1u1 + m2 u2 = (m1+m2)v

m1 and m2 are the masses of the bodies

u1 and u2 are the initial velocities

v is the final velocity after collision

Substitute the given values into the formula

1055(0) + 660(2) = (1055+660)v

0+1320 = 1715v

v = 1320/1715

v = 0.77m/s

Hence the final velocity of each vehicle is 0.77m/s
