The motor is towing the crate that has a mass of me = 1000 kg, and rests on the flat surface. It delivers
an increasing horizontal pulling force of T= 500 Newton, where t is in second, to its cable at A, after

which the force is kept constant at 5000 N. The coefficients of static friction and kinetic friction are
us =0.3 and uk =0.2, respectively, between the crate and the surface. Determine the velocity (m/s) of
the crate when t₂ = 5s.

The coefficient of kinetic friction between the block and the surface is p=0.4. If the block
is initially moving up the plane at ug-2 m/s, and at this instant (t=0) the motor
develops a tension in the cord of T (300+120) N. where t is in seconds, determine

17-A12 The wagon and load have a mass of 300-kg. No friction at A or B. The wheels are small and have no mass.
If P= 2000 N, what are the acceleration and normal forces at A and B?
Determine the maximum force P that can be applied such that all of the wheels stay on the ground. (You may
solve the problem by summing moments about G or about B. You should practice both ways.)
