A

`61-kg`

mother and her

`37-kg`

son are sledding down a

`20\deg `

incline when their

`8-kg`

toboggan hits a small bump and the son falls off the sled (he was not holding onto the toboggan as instructed by his mother). After one second, the mother jumps off the toboggan to see if her son is unharmed. The son leaves the toboggan with zero relative velocity, and the mother has a relative velocity of

`1(m)/(s)`

up the hill when she jumps off the toboggan. Knowing that the toboggan is initially traveling at

`5(m)/(s)`

and that the coefficient of kinetic friction between the toboggan and the ground is 0.35 , determine the speed of the toboggan immediately after the mother jumps off. The speed of the toboggan immediately after the mother jumps off is

`?`

`(m)/(s)`

.
