vf $=$ ufloat$(0\mathrm{.}085,0\mathrm{.}0041)$ # vf is the velocity of the combined cars after the collision

Exercise $1$b

case $($e$.$g$.$ from K$1$i to k$1$i $).$

Use $"$f$-$strings" to print your calculated values.

Make sure each quantity is printed with its correct unit. Follow the example for p$1$i $.$

Verify that your code produces sensible results.

$[]$: p$1$i $=$ m$1*$v$1$i # Momentum of m$1$ before collision

p$2$i $=$ m$2*$v$2$i # Momentum of m$2$ before collision

print$($f$\text{'}$Momentum of m$1$ before collision: $\{$p$1$i:eP$\}$ kg$$m$/$s$\text{'})$

print$($f$\text{'}$Momentum of m$2$ before collision: $\{$p$2$i:eP$\}$ kg$$m$/$s$\text{'})$

pi $=$ # Total momentum before collision

mtot $=$ # Combined mass

pf $=$ # Total momentum after collision

p$\_$ratio $=$ # Ratio of total momentum after$/$before collision
