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
