Question

The figure shows a small, initially stationary block released on a frictionless ramp at a height of 3.0 m. Hill heights along the ramp are as shown. The hills have identical circular tops, and the block does not fly off any hill. (a) Which hill is the first hill that the block cannot cross? (b) What does the block do after failing to cross that hill? On which hilltop is (c) the centripetal acceleration of the block greatest and (d) the normal force on the block least?

4 In Fig. 8-21, a small, initially stationary block is released on a frictionless ramp at a height of
3.0 m. Hill heights along the ramp are as shown in the figure. The hills have identical circular
tops, and the block does not fly off any hill. (a) Which hill is the first the block cannot cross? (b)
What does the block do after failing to cross that hill? Of the hills that the block can cross, on
which hilltop is (c) the centripetal acceleration of the block greatest and (d) the normal force on
the block least?
