In the ballistic pendulum experiment (A.K.A conservation of momentum & energy), the velocity of the projectile was measured
and recorded (vo = 3.94 m/s). The mass of the projectile was 12.1 g and the ballistic pendulum mass was 103.3 g. After the projectile is fired, it hits the ballistic pendulum, and both moved with velocity LaTeX: vv. If the pendulum length is 0.32 m, calculate the maximum angle that the ballistic pendulum (with projectile) reached after the collision.

Answer:
Position = behind the mirror
Nature = Virtual and Erect
Size = : Diminished
Explanation:
Sign convention-Distance measured to the left of pole is negative and to the right of pole is positive.
Object distance = u = -20 cm
Focal length = f = Radius of curvature/2 = 30/2 = 15 cm
We have to use mirror formula to find image distance.
Since the image distance is positive, it is formed behind the mirror or a virtual image is formed.
Magnification =
Height of the object = 5 cm
Height of the image =
Since the height of the image is positive and less than the size of object,it is erect and diminished.
