2. [-/10 Points] DETAILS SERCP7 4.P.020. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER Two people are pulling a boat through the water as in Figure P4.20. Each exerts a force of 600 N directed at a 0 = 25.0 angle relative to the forward motion of the boat. If the boat moves with constant velocity, find the resistive force F exerted by the water on the boat. 600 N Je 600 N Two packing crates of masses m, = 10.0 kg and my = 6.50 kg are connected by a light string that passes over a frictionless pulley as in Figure P4.26. The 6.50 kg crate lies on a smooth incline of angle 37.0. Find the acceleration of the 6.50 kg crate. m/s2 (up the incline) Find the tension in the string. my An object with mass m, = 4.00 kg, rests on a frictionless horizontal table and is connected to a cable that passes over a pulley and is then fastened to a hanging object with mass my = 8.0 kg, as shown in Figure P4.30. Find the acceleration of each object and the tension in the cable. mass m, m/s 2 mass m2 m/s 2 tension N IN2 Two objects with masses of 1.00 kg and 7.00 kg are connected by a light string that passes over a frictionless pulley as in Figure P4.34. Figure P4.34 (a) Determine the tension in the string. IN (b) Determine the acceleration of each object. m/s 2 (c) Determine the distance each object will move in the first second of motion if both objects start from 'est
