Aloaded 355 kg toboggan is traveling on smooth horizontal snow at 4.00 m/s when it suddenly comes to a rough region. the region is 6.60 m long and reduces the toboggan's speed by 1.00 m/s . what average friction force did the rough region exert on the toboggan?

Apositive point charge q is fixed on a very large horizontal frictionless tabletop. a second positive point charge q is released from rest near the stationary charge and is free to move. which statement best describes the motion of q after it is released? assume q stays on the table
