Kindly find the answers for the following questions, with complete solutions and some explanation on critical parts. Thank you.
1. Find the tension in each cord in the figure below if the mass of the suspended object is 2.0 kg. (а) (b) 30° 45 A 45 60 2. A large wrecking ball is held in place by two light steel cables. If the mass m of the wrecking ball is 3620 kg, what are (a) the tension Tg in the cable that makes an angle of 40° with the vertical and (b) the tension TA in the horizontal cable? 40° m 3. A 5.00-kg box is moving to the right with speed 3.00 m/s on a horizontal, frictionless surface. At t = 0 a horizontal force is applied to the box. The force is directed to the left and has magnitude F(t) = (8.00 N/s²)t². (a) What distance does the box move from its position at t = 0 before its speed is reduced to zero? (b) If the force continues to be applied, what is the speed of the box at t = 3.00 s? 4. Two blocks of mass 3.50 kg and 8.00 kg are connected by a massless string that passes over a frictionless pulley. The inclines are frictionless. Find (a) the magnitude of the acceleration of each block and (b) the tension in the string. 8,00 kg 3.50 kg 35.0° 35.0° 5. Block A weighs 45.0 N, and block B weighs 25.0 N. Once block B is set into downward motion, it descends at a constant speed. (a) Calculate the coefficient of kinetic friction between block A and the tabletop. (b) Suppose an object with a 45-N weight rests on top of block A. If block B is now set into downward motion, what is its acceleration (magnitude and direction)? A
