When the human body is at rest, the heart pumps 4.6 L of blood into the aorta every minute. During some exceptional exertion, such as playing sports, the amount of blood delivered to the aorta increases to 25 L every minute. If the area of the opening of the aorta is A = 0.81 cm2 What is the average velocity of blood as it enters the aorta in each of these cases?
You step onto a hot beach with your bare feet. A nerve impulse, generated in your foot, travels through your nervous system at an average speed of 139m/s. How much time does it take for the impulse, which travels at a distance of 1.81m, to reach your brain?
A cat chases a mouse across a 1.7 m high table. The mouse steps out of the way, and the cat slides off the table and strikes the floor 1.5 m from the edge of the table. The acceleration of gravity is 9.81 m/s 2 . What was the cat’s speed when it slid off the table? Answer in units of m/s.
Question 3. Siblings Alice and Bob saved their money all summer to buy a water balloon launcher, and they are eager to take it for a test run. Younger brother Bob thinks he's a pretty fast runner with a top speed of 5 m/s. Не poses the following challenge to his sister: "I'll stand 20 m from you and I'll start running away as soon as you launch a water balloon. See if you can hit me!" Unfortunately for Bob, Alice is a physics 8A ace and knows exactly what needs to be done to soak her brother. (a) Set the origin of your coordinate system at Alice's position with Bob starting along the positive x-axis (and running along the x-axis). Assuming Bob runs at a constant velocity, what is Bob's trajectory rB(t)? (b) Suppose the water balloon launcher is limited to only firing at an angle of T/4. In terms of the unknown initial launch speed v, what is the trajectory of the water balloon rwB(t)? (c) What speed v should Alice launch with to ensure a direct hit? (d) How long does the balloon take…
A person driving on I-82 glanced at his phone to read a very important text message. When he looked back up at the road, he saw that the traffic ahead had come to a standstill and he immediately slammed on his brakes. His car created 96.5 m long skid marks before rear-ending another car. Unfortunately, a passenger in the rear-ended car was seriously injured, thus requiring an investigation by the State Patrol. The State Patrol has no proof of distracted driving, however they want to determine if a citation for speeding should be issued. A State Patrol investigator used a 3.9 kg drag sled to determine the coefficient of kinetic friction between the road and the tires of the car. The drag sled’s spring scale read 28 N when it was pulled along the ground at a constant speed. Use Newton’s Second Law and kinematics to estimate the minimum value of the car’s speed when the driver locked the brakes. (answer: about 83 mi/hr) Note: You do not need the mass of the car to answer this…
True or False? Consider carts colliding on a straight level track. It is impossible for two identical carts moving at different speeds to collide and stick together and end up not moving.
In 1992, a 14-kg meteorite struck a car in Peekskill, NY, leaving a 20-cm-deep dent in the trunk. If the meteorite was moving at 500 m/s before striking the car, what was the magnitude of its acceleration while stopping? Find the time it takes for the meteorite to come to a complete stop.
You want to visit your friend in Seattle and decide to take the train. Unfortunately, you are late getting to the train station. You are running as fast as you can, but 30 meters ahead of you the train begins to pull out. You can run at a maximum speed of 8 m/s and the train is accelerating at 1 m/s². In 50 meters you will reach a barrier. Can you catch up to the departing train? Argue why you should or should not jump onto the moving train?
You are driving along a straight section of road at 13 m/s when 10 m in front of you a furry creature jumps out into the middle of the road. You instantly slam on your breaks, but the breaks lock so that you slide along the pavement with kinetic coefficient of friction between the tires and the pavement of 0.65. By what distance do you stop short of running over the furry creature or by what distance is your roadkill dinner behind you when your car finally comes to a halt? Note that the total mass of the car (including you) is 1360 kg, while the mass of the furry creature is 2.6 kg.
Two locomotives 70 kilometers apart are travelling on the same track towards each other, Engine A moves at 22 kilometers per hour east and engine B moves at 13 kilometersper hour west. At the instant both trains begin moving, an annoying mutant fly beginsflying from engine A towards engine B at 33 kilometers per hour . The instant it touchesB, it turns around and flies back. It goes on this way until the two locomotives collideand the mutant fly is finally squashed. So, before its untimely demise, a) what is the total distance the fly flew? b) the time it took till it was eliminated and c) the average velocity of the fly? how can i find this please
A skater with mass 66 kg is skating on a horizontal surface at a constant speed 4.2 m/s. There is a ramp ahead, and the skater has just enough speed to make it to the top of the ramp (meaning the speed at the top of the ramp is 0 m/s). What is the height of the ramp in the unit of meters? Use g = 10 m/s2 for the acceleration due to gravity.
The mass of the Earth is 5.98 × 10^24 kg. A 9.29 kg bowling ball initially at rest is dropped from a height of 3.59 m. The acceleration of gravity is 9.8 m/s^2. What is the speed of the Earth coming up to meet the ball just before the ball hits the ground? Answer in units of m/s.
