could you please help me with these two subquestions
The overworked Amazon delivery person is driving up a steep hill with an incline of 26° when a box they forgot to secure starts sliding toward the back of the truck. The 3.5 kg box starts from rest near the drivers seat and slides 2.1 m along the floor to the rear door. The coefficient of kinetic friction between the box and the floor is 0.36. What is the work done by the weight of the box? Wmg What is the work done by the Normal Force? WN What is the work done by the frictional force? Wf = = = J What is the net work done on the box? Wnet = What the change in kinetic energy for the box? AKE = How fast is the box moving just before it hits the rear door? Vfinal = S
3/170 The system is at rest with the spring unstretched when 0 = 0. The 3-kg particle is then given a slight nudge to the right. (a) If the system comes to mo- mentary rest at 0 = 40°, determine the spring con- stant k. (b) For the value k = 100 N/m, find the speed of the particle when 0 = 25°. Use the value b = 0.40 m throughout and neglect friction. C B b m Problem 3/170 A 1.256

The coefficient of kinetic friction between the m = 10.4 kg crate and the plane is u = 0.3. Initially, the crate is at the position 1 on the horizontal plane with a velocity v, = 14.8 m/s. The crate moves a distance D = 4 m before going upward on the incline plane that has an angle with the horizontal of e = 35 degrees. The initial state and the state at the bottom of the incline plane are at h = 0 m. Determine the distance L the crate will travel upward where it will be at rest. g = 9.81 m/s?. h Position 1 13.626 m O 12.161 m O 15.091 m O 10.052 m

The double pulley shown in the figure is formed by two wheels that are coupled to each other. The complete pulley (formed by the two wheels) has a mass of 15 kg and a turning radius of 110mm. Block A has a mass of 40 kg. If a force of 2 kN is applied to the tied rope of the inner pulley wheel, determine the speed of block A after 3 seconds. At the beginning, the whole system was at rest. Disregard the mass of the string and consider that the moment of inertia (kg.m²) of the complete pulley is given by IP = mko²where m is the mass of the pulley and Ko is the radiusspinning
