Question

Ball A Mass: 0.45 kg Velocity: 50 m/s Ball B Mass: 0.45 kg Velocity: 80 m/s Ball C Mass: 0.45 kg Velocity: 25 m/s Which ball has the greatest momentum?\

Answer 1

Definition formula for momentum: P = mv

So P(A) = 0.45 * 50 = 22.5 kgm/s

P(B) = 0.45 * 80 = 36 kgm/s

P(C) = 0.45 * 25 = 11.25 kgm/s

B has the greatest momentum

Answer 2

$p=mv\\\\ A)\\m=0.45kg\\v=50 \frac{m}{s} \\p=0.45kg\cdot50 \frac{m}{s}=22.5\;kg\cdot \frac{ m}{s} \\B)\\m=0.45kg\\v=80 \frac{m}{s} \\p=0.45kg\cdot80\frac{m}{s}=36\;kg\cdot \frac{ m}{s} \\C)\\m=0.45kg\\v=25 \frac{m}{s} \\p=0.45kg\cdot25\frac{m}{s}=11.25\;kg\cdot \frac{ m}{s} \\\\B\ \textgreater \ A\ \textgreater \ C$
