The screaming demons have entered a bobsled race. The sled run is at an angle of 29 degrees dr.floor has come up with a super slick bobsled with a coefficient of friction of 0.0112. The combined mass of the two dare devils and their bobsled is 200 kg. What will be the screaming demons acceleration down the bobsled run?

A rope is attached to Box A, and it is pulled on a rough surface due east with friction. The mass of Box A is 50 kg, and the tension force applied to the box is 100 N due east. If Box A is pulled by the tension force for 4.0 s, and the velocity changes from 0.1 m/s due east to 0.65 m/s due east during the time Box A is pulled, answer the following questions.  (a) What is the acceleration of Box A during the time it is pulled?  (b) What is the change in kinetic energy of Box A during the time it is pulled?  (c) What is the net work done on Box A by the tension force and the frictional force together? (d) What is the work done on Box A by the tension force alone?  (e) What is the work done on Box A by the frictional force alone?

While two forces act on it, a particle is to move at the constant velocity = (3.58 m/s) -(-3.26 m/s). One of the forces is F1 = (1.88 N) + (-5.85 N). What is the other force? Number i + i j Units

A sled of mass 96 kg is being pushed up a slope with an applied force of 862 N. The slope is inclined with an angle of 36 degrees with respect to the horizontal. The coefficient of friction between the sled and the hill is 0.26. The acceleration of the crate (in m/s2) is:
