1. The block which has a weight of 200 N and it is pulling at floor with the force of 100 N and attains a velocity of 14m/sec in a distance of 40 meters starting from rest. Compute the coefficient of Kinetic friction between the block and the floor.
2.An elevator weighting 22.2 KN moving downward with constant acceleration travels a distance of 30 m during the interval of time t= 0 to t=10s. Assuming the initial velocity is zero and neglecting all resistances, find the tension in the supporting cable during this time.
3. A box weighing 100 N is placed on the floor of a truck moving 60 km/hr horizontally. if the coefficient of friction between the box and the floor of the truck is 0.5, determine how far the truck move before the box stops slipping.

1. A block with weight W = 30 N is on a flat horizontal surface. You pull to the right with a force F = 16 N. There is gravity present and the coefficient of friction is static = 0.4 and kinetic - 0.25. You are also pulling straight up with an applied force of 12 N. Now what are: The normal force N-_ the frictional force f- the net force on the block Foot and acceleration a = 2....
