Question

A dart with a mass of 0.5 kg is thrown at \( 15 \mathrm{~m} / \mathrm{s} \) and sticks into a 1 kg apple hanging on a string. What is the velocity of the dart and apple just after the dart is embedded? \( \mathrm{M} 1 \mathrm{~V} 1 \mathrm{i}+\mathrm{M} 2 \mathrm{~V} 2 \mathrm{i}=(\mathrm{M} 1+\mathrm{M} 2) \mathrm{Vf} \) ? a \( \quad 5 \mathrm{~m} / \mathrm{s} \) ? b \( \quad 15 \mathrm{~m} / \mathrm{s} \) ? c \( \quad 0 \mathrm{~m} / \mathrm{s} \) ? d \( \quad 10 \mathrm{~m} / \mathrm{s} \)
