Answer:
vB = 12 m/s
W = 36 J
Explanation:
Potential energy converts to kinetic energy
½mv² = mgh
v = √(2gh)
vB = √(2(9.8)(7.1 - 0) = 11.796609... m/s
W = mg(hA) - mg(hB) = 0.8(9.8)(7.1 - 2.5) = 36.064 J
The correct answer is: <span>smaller than object, virtual and upright.
</span>
When the object is placed between the focal point and the vertex of a convex mirror, then the image formed will be <span>located behind the convex mirror. It will be virtual image and an upright image but reduced in size (i.e., smaller than the object)</span>
