The force F, acting in a constant direction on the 22-kg block, has a magnitude that varies with the position s of the block. When s = 0 the block is moving to the right at v = 6 m/s. The coefficient of kinetic friction between the block and surface is μk= 0.3. Determine how far the block must slide before its velocity becomes 15 m/sm/s. Express your answer to three significant figures and include the appropriate units. Hint 1for Part A. How to approach the problem Use the principle of work and energy for the particle, which states that the particle's initial kinetic energy plus the work done by all the forces acting on the particle as it moves from its initial to its final position is equal to the particle's final kinetic energy. Note that besides force FF shown in the figure, the friction force acts on the block during its motion. Hint 2for Part A. How to find the friction force The friction force is directly related to the normal reaction, which in turn equals…

What allows us to make the determination that the boxes arent moving at the same velocity after being released from rest? It seems to me we would base this off of each boxes resistance to friction, but in this problem they are moving on a smooth surface. And then in this problem, we consider the boxes to move at the same velocities after the spring is released? Please explain how we can make this judgement. This is the problem: The two blocks A and B each have a mass of 5 kg and are suspended from parallel cords. A spring, having a stiffness of k=60 N/m is attached to B and is compressed 0.3 m against A and B as shown. Determine the maximum angles θ\thetaθ and ϕ\phiϕ of the cords when the blocks are releasedfrom rest and the spring becomes unstretched.
The crate, which has a mass of 180 kg If it is originally at rest, determine the distance it slides in order to attain a speed of 9 m/s. The coefficient of kinetic friction between the crate and the surface is μk = 0.2. Please answer using 3 sig figs.
It takes 34 s for the 60-Mg tugboat to increase its speed uniformly to 25 km/h, starting from rest. The propeller provides the propulsion force F which gives the tugboat forward motion, whereas the barge moves freely. The barge has a mass of 84 Mg . (A) Determine the force of the rope on the tugboat. Express your answer to three significant figures and include the appropriate units. The answer is not 17145.882 or 12254.12 N
The crate, which has a mass of 120 kg, is subjected to the action of the two forces. If it is originally at rest, determine the distance it slides in order to attain a speed of 9 m/s.

Determine the deceleration of (a) a 2200-kg car and (b) a 1100-kg car, if thebrakes are suddenly applied so that all four tires slide. The coefficient of friction η=0.6 on the dry asphalt. (η = F/N where N is the normal force and F is the frictional force). Give the complete solution with free body diagram.
the vertical ground reaction force from a force plate during the contact phase for a 55 kg runner. If the initial vertical velocity of the runner when she first makes contact with the plate is directed 0.40 m/s downwards, determine the following:a) the vertical velocity (including direction andmagnitude) just as the runner comes off the plate at the end of ground contact. (Average net force includes the effect of gravity and thevertical ground reaction force acting on therunner) b) the average vertical ground reaction forceduring the ground contact phase of the run
The 18 000-kg F-35B uses thrust vectoring to allow it to take off vertically. In one maneuver, the pilot reaches the top of her static hover at 200 m. The combined thrust and lift force on the airplane applied at the end of the static hover can be expressed as F = (44t + 2500t2)i + (250t2 + t + 176 580)j, where F and t are expressed in newtons and seconds, respectively. Determine how long it will take the airplane to reach a cruising speed of 1000 km/hr (cruising speed is defined to be in the x-direction only).
