If you begin walking forward at 2.00 m/s relative to the ice, with what speed, relative to the ice, does the slab move?

About 80 g of blood is pumped from the heart during each heartbeat. The blood starts at rest and has a speed of about 0.60 m/s in the aorta. If the pumping takes 0.17 s, What is the magnitude of the average force on the blood?
You are pulling your younger sister along in a small wheeled cart. You weigh 65.0 kg and the combined mass of your sister and the cart is 35.0 kg. You are pulling the cart via a short rope which you pull horizontally. You hold one end of the rope and your sister holds the other end. If you are accelerating at a rate of 0.10 m s−2, the rope is inelastic, and the frictional force acting upon the cart is 30 N:

- A car traveling at 27.2 m/s hits a bridge abutment. A passenger in the car, who has a mass of 65.0 kg, moves forward a distance of 57.0 cm while being brought to rest by an inflated air bag. Assuming that the force that stops the passenger is constant, what is the magnitude F of this force?arrow_forwardA teenager is pushing a cart. There is no friction between the cart and the ground. Mass of the cart is 120 kg. Cart is initially at rest (at time = 0 s). Direction to the right is positive. He pushed the cart for 5 s (from t = 0 s to t = 5 s) with a force of 75 N to the right hand side. Then he stopped pushing for 5 s (from t = 5 s to t = 10 s). Then he pushed the cart for 10 s (from t = 10 s to t = 20 s) with a force of 75 N to the left hand side. Question: Calculate the work done on the cart from t = 0 s to t = 5 s.arrow_forwardA car of mass 1.2 103 kg is traveling east at a speed of 24 m/s along a horizontal roadway.

- A robot with fancy wheels is trained to move in two directions simultaneously. The force in the forward direction is 10 N and the force in the horizontal direction is 8 N. If the robot starts from rest, has a mass of 75 kg and travels for 100 seconds, what is the magnitude of the robot's final displacement?arrow_forwardWhile rollerblading through your neighborhood, you suddenly lose control and begin coasting down a hill, unable to stop. Fortunately, you see a neighbor moving a mattress into their house and decide that colliding with the mattress would be far less painful than the alternatives. Your plan works to perfection and you are slowed gently over the course of 1.4 seconds. Assuming your mass is 80 kg and your initial velocity was 10 m/s, find the average force applied on your body by the mattress (in N).arrow_forwardA waitress shoves a ketchup bottle with mass 0.45 kg to her right along a smooth, level lunch counter. The bottle leaves her hand moving at 2.8 m/s, then slows down as it slides because of a constant horizontal friction force exerted on it by the countertop. It slides for 1.0 m before coming to rest. What is the magnitude of the friction force acting on the bottle?arrow_forward

- The engines of a tanker broke down and the wind pushes the ship with a constant speed of 1.5 m / s straight towards a reef. When the boat is 500 m from the reef, the wind stops and the engineer manages to start the engines. The rudder is stuck, so the only option is to try to accelerate backwards. The mass of the ship and its cargo is 3.6 x 107 kg and the engines produce a net horizontal force of 8 x 104 N. The hull can withstand impacts at a speed of 0.2 m / s or less. The retarding force that the water exerts on the hull of the ship can be neglected. a) The equation of motion that corresponds to the horizontal component is? b)The acceleration of the ship is equal to? c) If the reef does not exist, the vessel, before stopping, travels what distance?arrow_forwardYou go trick-or-treating with your friends and end up with more candy than you know what to do with. You get tired of carrying your pillowcase full of candy, so you start to drag it along the ground. Your pillowcase has a mass of 8.7 kg and the coefficient of kinetic friction between your pillowcase and the ground is 0.20. It's time to catch up to your friends, so you take off, still dragging the bag. You pull on the bag with a force of 62 N at an angle of 57 degrees above the horizontal. - What is the magnitude of the Normal force acting on the bag? - What is the magnitude of the kinetic friction force acting on the bag? - What is the net acceleration of the bag?arrow_forwardA 670 N student stands in the middle of a frozen pond having a radius of 6.9 m. He is unable to get to the other side because of a lack of friction between his shoes and the ice. To overcome this difficulty, he throws his 2.9 kg physics textbook horizontally toward the north shore at a speed of 6.9 m/s. The acceleration of gravity is 9.81 m/s².
