Answer:
Use the range formula - R = V^2 sin 2θ / g
A: R = V^2 sin 80 / g = .985 V^2 / g
B: R = V^2 sin 100 / g = .985 V^2 / g

Answer:
v = 6 cm
Explanation:
We have,
A small object is placed on the principal axis of a convex mirror of focal length 10 cm. The focal length of a convex mirror is positive. So, f = +10 cm
It is required to find the position of the image when the object is 15 cm from the mirror. Using mirror's formula :
v is image distance
Hence, the image will formed at a distance of 6 cm form the mirror.
