Question

Two object of mass 100g and 200g moving along the same line and direction with velocity 2m/s and 1m/s respectively the colite an after the collision, first object moves with velocity of 1.67m/s. Find the velocity of second object?

Answer 1

$\huge\underline\mathfrak{Object\:1:}$

Mass, $\sf{M_1}$= 100g = 0.1kg.

Initial velocity $\sf{U_1}$ = 2 ms-¹

$\huge\underline\mathfrak{Object\:2:}$

Mass, $\sf{M_2}$= 200g = 0.2 kg.

Initial velocity, $\sf{U_2}$= 1ms-¹

Final velocity, $\sf{V_1}$= ?

$\sf{Final\:velocity\:V_1=1.67\:ms^-1}$

By law of conservation of momentum,

$\sf{M_1U_1+M_2U_2=M_1}$

$\sf{V_1+M_2U_2}$

Second velocity $\sf\frac{0.4-0.167}{0.2}=1.67ms^-1$

$\bold{\large{\boxed{\sf{\pink{V_2=1.67ms^-1}}}}}$
