Question

) A 5 kg ball A strikes a 1kg ball B that is initially at rest. It is possible that after the impact A is not moving and B has a speed of 5v

Answer 1

Answer:

yes, this is true statement

Explanation:

given data

mass m1 = 5 kg

mass m2 = 1 kg

speed v =  5v

to find out

It is possible that after the impact A is not moving and B has a speed of 5v

solution

first we get here initial momentum that is express as

initial momentum = m1v1 + m2v2

initial momentum =  5×V + 1 × 0

initial momentum =  5V

and

now we get final momentum

final momentum  = m2v2+ m1v1

final momentum  = 1 × 5V + 5 × 0

final momentum  = 5v

so here we can say momentum is conserved

so this is the case of pure elastic collision

so we can say yes, this is true statement
