A sled weighs 10.0 kg. It is held in place on a frictonless 20.0 degree slope by a rope attached to a stake at the top of the slope. Find the tension in the rope if it is parallel to the slope.
A 1,075 N pole is held in place by a light wire at an angle = 24.5° to the horizontal as shown in the figure. The pole is attached to a pivot at the bottom, and a mass of weight w = 2,375 N hangs from its top. The pole makes an angle of d = 65.5º with the horizontal. Assume the pole is uniform. m (a) Find the tension in the supporting wire (in kN). KN (b) Find the...

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....

Sample Class Problems-Force and Acceleration Prob#l: Two people are pushing a stalled car (the mass of the car is 1850kg). One person applies a force to the car, while the other applies a force of 395N. Both forces act in the same of 560N also acts on the car, but in a direction opposite force arises because of friction and the extent to which the pavement opposes Find the acceleration of the car. direction. A third force to that in...
