Answer to three sig figs.
The coefficient of kinetic friction for a 19.75-kg bobsled on a track is 0.10. What force is required to push it down along a 6.0° incline and achieve a speed of 60.0 km/hr at the end of 75.0 m?

1. A 300 kg piano slides 4.7 m down a 30 degree incline and is kept from accelerating by a man who is pushing back on it parellel to the incline. The effective coefficient of kinetic friction is 0.35. Calculate the force exerted by the man. 2. A box is given a push so it slides across the floor. How far will it go, given that the coefficient of kinetic friction is 0.25 and the push imparted an initial speed...
Kasey needs to figure out the coefficient of kinetic friction between a wooden block and a metal track. She raises the track to 40 degrees above the horizontal and notices that the mass moves down the incline at a constant speed. What is the coefficient of kinetic friction?
Assume the block has a mass of 16 kg and the coefficient of kinetic friction is 0.86 in the following figure. What applied force P directed down and along the incline will produce an acceleration of 0.8 m/s2 down the incline? Force (P) = Number Newtons 35°
A block slides down a 20 degree incline. The coefficient of kinetic friction between the block and incline is 0.1. Use g = 10 m/s^2. If the magnitude of the blocks acceleration is 2.5 m/s^2 then find the minimum coefficient between the block and the incline such that the block can remain at rest when placed on the incline.
1) Let's practice calculating the frictional force of a skier on old "woody" skis and wet snow. The skier has a mass of 58 kg. The coefficient of kinetic friction of wood skis on wet snow is 0.1 Notice there are no units for the coefficient of friction. What is the kinetic frictional force between the wood skis and the snow? Answer: ?? 2) Do you remember Newton's 2d Law? F = ma? What is the magnitude (meaning we are...
A 5 kg block rests on a 30 degree incline. The coefficient of static friction between the block and the incline is .20. How large a horizontal force must push on the block if the block is to be on the verge of sliding A) up the incline and B) down an incline Answer: A) 43 N B) 16.6 N What would be the work to get me to this answer?
A 3.00-kg block is moved up a 37-degree incline by a constant horizontal force of 40.0 N. The coefficient of kinetic friction is 0.10, and the block is displaced 2.00 m up the incline. Note: The applied force is not parallel to the incline. Calculate the work done by gravity and the work done by friction.
