Q. You pull with a force of 295 N on a rope that is attached to a block of mass 20 kg, and the block slides across the floor at a constant speed of 1.2 m/s. The rope makes an angle of 35 degrees with the horizontal.
A. What is the direction of rate of change of momentum of the block?
B. What is the net force on the block?
C. Which objects exert forces on the block with nonzero x-components? (you, rope, earth, floor)
D. What is the x-component of the tension force exerted by the rope on the block? (A component may be positive or negative)
E. What is the x-component of the force exerted by the floor on the block (the friction force)?
F. Which objects exert forces on the block with nonzero y-components? (you, rope, earth, floor)
G. What is the y-component of the force exerted by the rope on the block?
H. What is the y-component of the force exerted by the Earth on the block?
I. What is the y-component of the force exerted by the floor on the block (sometimes called the "normal" force, because it is perpendicular to the floor)?
