A fielder tosses a 0.15 kg baseball at 36 m/s at a 27 ∘ angle to the horizontal. Part A: What is the ball's kinetic energy at the start of its motion? Part B: What is the kinetic energy at the highest point of its arc?
2. In the mechanism shown in Fig.2, the driving link is link A"A and the angle measured from the positive x-axis to this link is θ2 θ+ Φ. AA0.9 in A*B* = 1.7 in AB- 2.6 in h0.8 in 8-6" B* 120° Figure 2: (a) What is the mobility of the mechanism (b) Using the loop equation, derive an expression for the length AB and angle θ4 between link 4 and the horizontal asa function of the input angle θ2.
27 In Fig. 6-31, two blocks are connected over a pulley. The mass of block A is 10 kg, and the coefficient of kinetic friction between A and the incline is 0.20. Angle theta of the incline is 30°. Block A slides down the incline at constant speed. What is the mass of block B?

+8+7 ( 1800) (8d) 3. To find the distance across a highway, a surveyor chooses points A and B, which are (100 +10*N) m apart on one side of the highway (see Fig. 2; the highway is located between the side e and a reference point C- the vertex of the triangle). She then chooses the reference point C on the opposite side of the highway and finds that the angle a (70- N)0 and angle B-(.Approximate the distance afrom...

Consider the arrangement of the four initially uncharged capacitors shown in Fig. 25-36. Capacitors A, B, C, and D have capacitances 5.4 muF, 4.3 muF, 3.2 muF, and 2.1 muF, respectively. Suppose that a battery applies a potential difference of 3000 V across the circuit, which is then disconnected from the battery. What is the potential difference across each capacitor?
