Static and Kinetic Friction:
A 10 kg crate is at rest on a horizontal table (s =0.8, k =0.4). Then various amounts of horizontal pushing force are applied to it.
a.) The largest pushing force that can be applied before the crate starts moving is of size:
N
b.)-d.) If the pushing force were instead the two amounts shown below, please fill in the rest of the values on the chart below:
horizontal pushing force: friction force: (size only)
(indicate static or kinetic):
net force on crate:
(size only)
acceleration of crate:
(size only)
13 N N, ---Select--- static kinetic N m/s2
115 N N, ---Select--- static kinetic N m/s2
