Q3. One ball of mass m = 0.7 kg is being swung in the vertical, circular path with radius of r = 2.3 m. At the instant shown, the ball is moving at a speed of v = 5.8 m/s. Determine the tension force in the cable OA. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point, and proper Sl unit. Take g = 9.81 m/s². Your Answer: Answer A 45° units
3A. A 100-N block on a rough 30o-incline is acted upon by a force P as shown causing it to accelerate at 2 m/s2 up the plane. The coefficient of kinetic friction is 0.30. (a) Draw the FBD of the block (b) Find the magnitude of P.
Problem 1. Find the horizontal force magnitude P needed to start the motion of the block with mass mo in two scenarios: (a) when P is applied to the right and (b) when P is applied to the left. Develop a general solution for each scenario, and subsequently, substitute the values 0= 25°, m = mo = 2.5 kg, µs = 0.40, and μk = 0.35 into your expressions for evaluation.

Problem 2: A rocket is launched from the ground, straight up, from rest. The expelling gases from the bottom of the rocket provide it with a constant upward acceleration a. After 20 sec, the rocket reaches a height of 6500 m. At this point, the rocket depletes its fuel supply and the engines of the rocket are no longer working. At this point, the rocket goes into free fall, with an acceleration of –9.8 m/sec2. The left part of the figure below applies to parts (a)-(b). (a) What is the rocket's initial upward acceleration a? (b) What is the rocket's speed v, 20 sec after take-off? Hint: The answer is v = 650 m/sec. For parts (c)-(d), the rocket engines are now off. We will redefine the time to t = 0. The final properties for when the engines were on make the initial properties for when the engines are off: y0 = 6500 m, vo = 650 m/sec, and the acceleration is now a = -g, with g = 9.8 m/sec?. The right part of the figure below applies to parts (c)-(d). (c) What is ymaz, the largest height…
