Problem 7: Mira and Tariq are lab partners for the Pulley and Bricks Lab. They have determined that the \( 2.15-\mathrm{kg} \) brick is experiencing a forward tension force of \( 9.54 \mathrm{~N} \) and a friction force of \( 8.69 \mathrm{~N} \) as it is accelerated across the table top. Construct a free body diagram depicting the types of forces acting upon the brick. Then determine the net force and acceleration of the brick. Problem 8: Skydiving tunnels have become popular attractions, appealing in part to those who would like a taste of the skydiving experience but are too overwhelmed by the fear of jumping out of a plane at several thousand feet. Skydiving tunnels are vertical wind tunnels through which air is blown at high speeds, allowing visitors to experience bodyflight. On Natalya's first adventure inside the tunnel, she changes her orientation and for an instant, her \( 46.8-\mathrm{kg} \) body momentarily experiences an upward force of air resistance of \( 521 \mathrm{~N} \). Determine Natalya's acceleration during this moment in time. Problem 9: A rope is used to pull a \( 2.89-\mathrm{kg} \) bucket of water out of a deep well. a. What is the acceleration of the bucket when the tension in the rope is \( 30.2 \mathrm{~N} \) ? b. If starting from rest, what speed will the bucket have after experiencing this force for \( 2.16 \) seconds? Problem 10: A 1370-kg car is skidding to a stop along a horizontal surface. The car decelerates from \( 27.6 \mathrm{~m} / \mathrm{s} \) to a rest position in \( 3.15 \) seconds. Assuming negligible air resistance, determine the coefficient of friction between the car tires and the road surface.
