A 4.0 kg toboggan rests on a frictionless icy surface, and a 2.0 kg block rests on top of the toboggan. The coefficient of static friction µs between the block and the surface of the toboggan is 0.58, whereas the kinetic friction 16.T op coefficient is 0.48. The block is pulled by a horizontal force of 30 N as shown.
a. Calculate the block's acceleration.
b. Calculate the toboggan's acceleration
If the applied force is gradually reduced, at what value do the block and the toboggan have the same acceleration?
