Professional Application Football coaches advise players to block, hit, and tackle with their feet on the ground rather than by leaping through the air. Using the concepts of momentum, work, and energy, explain how a football player can be more effective with his feet on the Ground.
Unreasonable Results Squids have been reported to jump from the ocean and travel 30.0 m (measured horizontally) before re-entering the water. (a) Calculate the initial speed of the squid if it leaves the water at an angle of 20.0 , assuming negligible lift from the air and negligible air resistance. (b) The squid propels itself by squirting water. What fraction of its mass would it have to eject in order to achieve the speed found in the previous part? The water is ejected at 12.0 m/s; gravitational force and friction are neglected. (c) What is unreasonable about the results? (d) Which premise is unreasonable, or which premises are inconsistent?
Two carts on an air track have the same mass and speed and are traveling towards each other. If they collide and stick together, find (a) the total momentum and (b) total kinetic energy of the system, (c) Describe a different colliding system with this same final momentum and kinetic energy.
Professional Application Explain in terms of momentum and Newton's laws how a car's air resistance is due in part to the fact that it pushes air in its direction of motion.
Calculate the final speed of a 110-kg rugby player who is initially running at 8.00 m/s but collides head-on with a padded goalpost and experiences a backward force of 1.76104N for 5.50102 s.
Professional Application Consider the following question: A car moving at 10 m/s crashes into a tree and stops in 0.26 s. Calculate the force the seatbelt exerts on a passenger in the car to bring him to a halt. The mass of the passenger is 70 kg. Would the answer to this question be different if the car with the 70-kg passenger had collided with a car that has a mass equal to and is traveling in the opposite direction and at the same speed? Explain your answer.
You are standing on a very slippery icy surface and throw a 1-kg football horizontally at a speed of 6.7 m/s. What is your velocity when you release the football? Assume your mass is 65 kg.
Two 70-kg canoers paddle in a single, 50-kg canoe. Their paddling moves the canoe at 1.2 m/s with respect to the water, and the river they’re in flows at 4 m/s with respect to the land. What is their momentum with respect to the land?
Coal miners love physics, and in their spare time, they like to do physics experiments. One popularexperiment involves using a sling shot to shoot lumps of coal into coal carts and seeing how far the carts movealong the track as a result. One particular miner shoots a 5.0-kg lump of coal horizontally of a 10-m highledge into a 90-kg cart waiting below, as shown. If the lump of coal has an initial speed of 30 m/s and thecart moves 0.80 m after the coal lands inside it, how much work did the friction between the cart and thetrack do on the cart? Also, what is the coefcient of kinetic friction between the cart and the track? Hint: you can assume that friction is the only force acting on the cart in the horizontal direction.
Two astronauts are facing off in a fight outside the International space station. Astronaut Pitt (78 kg) and astronaut Reeve (80 kg) are initially at rest with respect to each other. Pitt pushes Reeve hard towards the earth at a speed of 3 m/s. Ignoring friction, What is the velocity of Pitt after the push? 2. What is the minimum amount of chemical energy that is converted into mechanical energy in Pitt’s muscles from his action?
The Hulk (210 kg of pure angry muscle) collides head-on with a truck (2,970 kg). If the Hulk was running at 10 m/s and the truck was moving at 22 m/s in the opposite direction, after they stick together, what is their speed (in m/s)? (Hint: be careful about directions here, either the Hulk or the truck needs a negative initial velocity, I've left it up to you which one gets that negative initial velocity, but the final answer is just the speed, so if you wind up with a negative final velocity, drop the minus sign)
A 56 kg ice skater traveling at 4.0 m/s to the north suddenly grabs the hands of a 65 kg skater traveling at 12 m/s in the opposite direction. The two skaters continue to travel with their hands joined. What is the final velocity of the two skaters? What is the decrease in kinetic energy for the system?
