Answer:
magnitude of vector is 276.19 kg m/s
Explanation:
The initial momentum is vector of magnitude
And driven in a coherent manner with initial vector.
same magnitude is momentum after the impact, but it is oriented perpendicularly to initial momentum vector.
So, you have 2 momentum vector of specified magnitude perpendicular to one another.
The contrast between such two vectors is a right angle triangle hypotenuse of 195.3 sides
magnitude of vector is 
Answer:30 cm
Explanation:
Given
object distance 
focal length of concave mirror 
height of object 
Using mirror formula




and magnification is



So height of object is same as of object .
Position :image is formed at the spot where object is placed.
