Q24. As shown in the image below, the 16-kg block A and the 42-kg block B connected by the weightless, frictionless pulley system are released from rest. Determine the speed of block B when block A has displaced downwards by 0.7 m. Please pay attention: the numbers may change since they are randomized. Your answer must include 3 places after the decimal point, and proper Sl unit. A Answer: d O [o k B

Move over Jeff Bezos, this invention is about to make you the richest person in the world. You have just invented the OyOy (that's YoYo spelled backwards). It is the very latest in home safety and so easy to use! If your building is on fire, simply reach out and grab the cord on the Oyoy and you will be lowered safely toward the ground at a low velocity. The OyOy has a total mass M = 106.0 kg and is shaped like a cylinder of radius R = 0.835 meters. The secret to the operation of the OyOy is its patented shaft whose radius is only r = 0.0830 meters. The cord is wound around the small shaft and this is the secret to your low velocity. Outer Radius = R Spindle Radius = r Mass = M The FORMULA for the moment of Inertia: I = V(y=0)=? We will use the approximation that the shaft is of negligible mass compared to the total. This means that you can treat the entire OyOy as though it is a solid cylinder with mass M and radius R. Imagine that a customer of mass m = 77.5 kg is using the Oyoy and…

7) A 5-kg body A is released from rest on a frictionless circular surface. The body then moves on a horizon- tal surface CD whose coefficient of friction with the body is 0.2. A spring having a spring constant K = 900 N/m is positioned at C shown in the diagram. How much will the spring compress? K -10 m- 7 m 8) For the system in Question 7, what is the velocity of block A each time it passes point D? 9) For the pendulum in Question 7, what is the maximum normal acceleration of the block?
