step by step show all work please A block of mass m1= 3.00 kg sits on top of block m2 = 6.00 kg, which sits on a horizontal frictionless table. You apply a force F=30.0 N to the right on the bottom block and both blocks accelerate to the right but they do not move together as a unit. There is friction between the blocks withμk= 0.200. a) Draw an FBD for each block. b) Solve for the magnitude of the friction force acting on each block (N). c) Solve for the magnitudes of accelerations of m1 and m2, and call them a1 and a2.

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 cocfficient of kinctic friction of 0.15 as shown in Figure (a). (B) Suppose the force F is applied at an angle 6 as shown in Figure (b). At what angle should the force be applied to achieve the largest possible kinetic energy? (а) (b)

A 50.0 kg grindstone is a solid disk 0.530 m in diameter. You press an ax down on the rim with a normal force of F = 160 N. The coefficient of kinetic friction between the blade and the stone is 0.60, and there is a constant friction torque of 6.50 N⋅m between the axle of the stone and its bearings. a) How much force must be applied tangentially at the end of a crank handle 0.500 m long to bring the stone from rest to 120 rev/min in 7.00 s? b) After the grindstone attains an angular speed of 120 rev/min, what tangential force at the end of the handle is needed to maintain a constant angular speed of 120 rev/min? c) How much time does it take the grindstone to come from 120 rev/min to rest if it is acted on by the axle friction alone?

A block is held against a compressed string when it is released from rest. It then slides around a vertical loop without friction. The setup is shown. A www Rough Smooth A) In terms of the mass of the block m, spring constant k, radius of the loop, R, and the acceleration due to gravity, g. What is the minimum compression distance (from relaxed length) of the spring if the block is to make it around the loop without leaving the track? B) After exiting the loop, the block encounters a rough surface where the coefficient of kinetic friction between the block and the rough surface is µ. What is the minimum stopping distance on the rough surface needed if the block had the minimum speed to stay on the track from part a?
