Question

a body p has ke energy e. another body q,whose mass is 9 times than p,also has kinetic energy E. calculate the ratio of velocities of p and q.​

Answer 1

Answer:

3:1

Explanation:

according to question

mass of P=m

mass of q=9m

kinetic energy of p= E

also kinetic energy of q=E

then clearly, E=E

1/2×m×v^2=1/2×m'×v'^2

(v/v')^2=m'/m

=9m/m

(v/v')=√(9/1)

(v/v')=3/1

so ratio of velocity of p & q

v:v'=3:1

Answer 2

Answer:

Ans is 3:1
