A block is given a short push and then slides with constant friction across a horizontal floor. Which statement best explains the direction of the force that friction applies on the moving block? - Friction will be in the opposite direction of the block's motion because thermal energy generated at the interface between the block and the floor converts some of the block's kinetic energy to potential energy. - Friction will be in the same direction as the block's motion because molecular interactions between the block and the floor will deform the block in the direction of motion. -Friction will be in the same direction as the block's motion because thermal energy generated at the interface between the block and the floor adds kinetic energy to the block. - Friction will be in the opposite direction of the block's motion because molecular interactions between the block and the floor will deform the block in the opposite direction of motion.
Current Attempt in Progress Flying Circus of Physics The high-speed winds around a tornado can drive projectiles into trees, building walls, and even metal traffic signs. In a laboratory simulation, a standard wood toothpick was shot by pneumatic gun into an oak branch. The toothpick mass was 0.11 g, its speed before entering the branch was 227 m/s, and its penetration depth was 16 mm. If its speed was decreased at a uniform rate, what was the magnitude of the force of the branch on the toothpick? Number Units

A surgeon is using material from a donated heart to repair a patient's damaged aorta and needs to know the elastic characteristics of this aortal material. Tests performed on a 16.0 cm strip of the donated aorta reveal that it stretches 3.31 cm when a 1.80 N pull is exerted on it. For related problem-solving tips and strategies, you may want to view a Video Tutor Solution of Fishy business. Part A) What is the force constant of this strip of aortal material? Express your answer in newtons per meter. Part B) If the maximum distance it will be able to stretch when it replaces the aorta in the damaged heart is 1.96 cm, what is the greatest force it will be able to exert there? Express your answer in newtons.
A vehicle applies it breaks for 102 ft before departing the roadway. The roadway surface friction factor is 0.50. The vehicle continues to break on an unpaved surface with a fiction factor of 0.30, for another 30 ft. The vehicle then strikes a stationary object with an impact of 20 mph. What was the initial speed of the vehicle? The roadway and unpaved surface are level.
