3 points g Figure 1 below shows two masses attached using a pulley system. Block m4 has a mass of 1.0 kg and block m5 has a mass of 2.0 kg. Suppose the pulley is massless and there is no friction. What is the tension in the rope when the blocks, initially at rest, starts accelerating due to gravity only? Assume frictionless surface. Note: g = 9.81 m/sec? m; Figure 1 Steps involved in solving this problem: A. Draw the freebody diagram indicating the forces (weight of two masses, tension, etc.). Do not draw the freebody diagram on top of the picture above. Do it separately. B. Show the direction of acceleration for each mass. C. Write down the equations using Newton''s second law (one for each mass and solve for the unknown, T) _A pickup truck weighing 30,000 Newtons was driven up a distance of 1600 m along a hill and reaches level (flat) area that is 800 meters above the starting point (i..e height from the base is 800 m). If the trip took 8 minutes with no breaks, what was the minimum power needed on the truck? Useg = 9.81 m/sec2. Show proper calculations and proper units. Step 1: Calculate the mass (m) of the truck. Step 2: Use PE = m.g.h to calculate the Potential Energy (PE) gained by the truck. Step 3: Note work done is change in PE. Step 4: Use the formula, Power = YerkDone =, 1o calculate the effective or minimum power needed
