What isthe magnitude of the object's accleration?Two crates connected by a rope lie on a horizontal surface. Crate A has mass mA, and crate B has mass mB. The coefficientof kinetic friction between each crate and the surface is mk. Thecrates are pulled to the right at constant velocity by a horizontal forceF vector. Draw one or more free-body diagrams to calculate the following interms of mA, mB, and mk: (a) the magnitude of F vector and (b) the tension inthe rope connecting the blocks.The tension in a violin string is2.7 N. When pushed down against the neck of the violin, the stringmakes an angle of 4.1° with the horizontal. (a) With what forcemust you push down on the string to bring it into contact with theneck? (b) If the angle were less than 4.1°, would the required forcebe greater than, less than, or the same as in part (a)? Explain.

What is thenormal force from the ramp on your friend?A box full of books rests on a wooden floor. The normal forcethe floor exerts on the box is 238 N. (a) You push horizontally on the box with a force of126 N, but it refuses to budge. Whatcan you say about the coefficient of static friction between thebox and the floor? Hs> (b) If you must push horizontally on the box with a force of atleast 135 N to start it sliding, whatis the coefficient of static friction? (c) Once the box is sliding, you only have to push with a force ofl17 N to keep it sliding. What is thecoefficient of kinetic friction?
- A 45.0-kg crate of tools rests on a horizontal floor. You exert a gradually increasinghorizontal push on it and observe that the crate just begins to move when your forceexceeds 313 N. After that you must reduce your push to 208 N to keep it moving at asteady 25.0 cm/s. (a) What are the coefficients of static and kinetic friction between thecrate and the floor. (b) what push must you exert to give it an acceleration of 1.10 m/s2 ?At one moment during a walk around the block, there are four forces exerted upon Fido - a 10.0 kg dog. The forces are: Fapp = 67.0 N at 30.0° above the horizontal (rightward and upward)Fnorm = 64.5 N, upFfrict = 27.6 N, leftFgrav = 98 N, down Resolve the applied force (Fapp) into horizontal and vertical components, then add the forces up as vectors to determine the net force.A 20-kg equipment is initially at rest on an inclined surface with a 15° angle with the horizontal.A force 75N sets the crate in motion.

- Two boxes (Box A = 9.7 kg and Box B = 5.4 kg) are connected by acord running over a pulley. The coefficient of kinetic friction betweenbox A and the table is 0.18. We ignore the mass of the cord and pulleyand any friction in the pulley, which means we can assume that a forceapplied to one end of the cord will have the same magnitude at theother end. We wish to find the tension of the cord while accelerating (inN), assuming the cord doesn’t stretch. As box B moves down, box Amoves to the right. Hint: Solve for the acceleration of the system first.*66. The person in the drawing isstanding on crutches. Assume thatthe forceexerted on each crutch by the groundis directed along the crutch, astheforcevectors in the drawing indicate. If the coeffi -cient of static frictionbetween a crutch andthe ground is 0.90, determine the largestangleuMAX that the crutch can have just beforeit begins to slip on thefl oor.The block A with a mass of 10 kg is pushed up the 25o inclined plane by applying a force F on it.
