please help with 1,2 and 3 (explain with drawing as well as work pls)

Lab 5: Pre-Lab Questions (16 pts.) 1. Assume that you are studying a cart and mass system like the one shown in Figure 1. Given m1 = 20 kg, m2 = 30 kg, and 0 = 35, find the acceleration , a, and the tension, T, of the system. (8 pts.) 2. What if you know the acceleration but not the mass? Given m1 = 45 kg, 0 = 40, and a = -3.2 m/s2 (down the slope), what is mass m2? (5 pts.) 3. Consider the setup shown in Figure 1 and the free-body diagrams in Figure 2. Is it possible for the acceleration of the system to be uphill if m2
