: 4 A 3 00 Kg Mass Is Initially At Rest On A Horizontal Surface After Some Amount Of Time The Has A Velocity Of 12 0 M 1 (13.24 KiB) Viewed 95 times

a) What was the net work done on the object over this time?
b) If an applied force of 75.0 N i was acting and the displacement over which the change in velocity took place was 4.00 mi, what was the work done by the applied force during this time?
an applied force of 75.0 Ni was acting and the displacement over which the change in
ity took place was 4.00 m i, what was the work done by the force of kinetic friction during this time?
d) Regarding part c, what must the coefficient of kinetic friction be?
