- Q1) A 5 kg block initially at rest is pulled to the right along a horizontal surface by a constant horizontal force of 12 N. (A) Find the speed of the block after it has moved 4 m if the surfaces in contact have a coefficient of kinetic friction of 0.15 as shown in Figure (a). (B) Suppose the force F is applied at an angle 0 as shown in Figure (b). At what angle should the force be applied to achieve the largest possible kinetic energy? (a) (b)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.Just 5 please

- 2-12) A block has a mass 1989 grams and is setting on a flat, frictionless surface. The block is pushed along until it has a speed of 3.31 m/s. That force is removed, and then a short time later another force pulls upon the block via a massless rope angled at 26.6 degrees above the horizontal as shown below. The force is steady at 16.63 mN and acts for 33.3 seconds. So, what is the final speed of this block after this process? a)12.7 m/s b) 3.56 m/s c) 1.8 m/s d) 1.9 m/s e) 7.1 m/s2. Determine the velocity of the 60-lb block A if the two blocks are released from rest and the 40-lb block B moves 2 ft the incline. The coefficient of up kinetic friction between both blocks and the inclined planes is u, =0.10. %3D Use Constraint Equations (for pulley), Equation of Motion (Newton's second law), and the Principle of Work and Energy.
