$\backslash ((\backslash$# $2\backslash )$

Cart $\backslash ($ C $\backslash )$ and box B start at rest.

Imagine a $40$ g chewing gum ball is shot horizontally with velocity $\backslash (150\backslash$mathrm$\{$~m$\}/\backslash$mathrm$\{$s$\}\backslash ).$ The chewing gum hits box $\backslash ($ B $\backslash ),$ which has mass $6$ kg $.$ After the impact, the chewing gum sticks to the box and slides to the end of cart $\backslash ($ C $\backslash )$ where it

$-($A$)$ impacts the handles.

The cart has mass $115$ kg $.$

After Box B and gum A impact the cart they all slide togethe Impulsive forces can be neglected

Using conservation of momentum, find the velocity of the chewing gum and box after the first collision.

Then find the velocity of all three objects after the second impact.
