A sled of mass 50.0 kilogram is pulled along flat, snow-covered ground. The kinetic friction coefficient is 0.10, and the static friction coefficient is 0.30.
(a) Determine what does the sled weigh?
N
(b) Find what force will be needed to start the sled moving?
N
(c) Find what force is needed to keep the sled moving at a constant velocity?
N
(d) Once moving, determine what total force must be applied to the sled to accelerate it at 2.8 m/s2?
