Richard rides a bike on a road sloping downward and inclined at an angle of 30° with the horizontal. If he moves at a constant speed of 10 meters/second, calculate his vertical downward velocity.

Explanation:

The vertical downward component of the speed of the bike can be simply found out by using the following geometric formula:

where,

= vertical downward component of speed = ?

v = speed = 10 m/s

θ = angle of slope = 30°

Therefore,

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.
