A block of mass m is pulled a distance L across the ground by a constant force Fp. The force of the pull, Fp, is at an angle e to the floor. The coefficient of sliding friction is H, and the coefficient of static friction is neglected (i.e., we are considering the problem at the instant the block begins to move, so we will not consider static friction). We will calculate the final velocity of this block. (a) Draw a free body diagram of the block.

Transcribed Image Text:A block of mass m is pulled a distance L across the ground by a constant force Fp. The
force of the pull, Fp, is at an angle 0 to the floor. The coefficient of sliding friction is H,
and the coefficient of static friction is neglected (i.e., we are considering the problem at the
instant the block begins to move, so we will not consider static friction). We will calculate
the final velocity of this block.
(a) Draw a free body diagram of the block.
(b) What is the magnitude of the normal force?
Transcribed Image Text:(c) Using Newton's second law, compute the acceleration of the block.
(d) Using the equations of linear motion, write a symbolic expression for the velocity of the
block after it has traveled a distance L.
