Energy Scramble For each of the problems, solve for the desired variable. There will only be 4 unique answers across all 15 problems. DO NOT ROUND until the very end. For all problems that have the same answer related by factors of 10, unscramble the letters to form a word. What do these words have in common?
A car covers a distance of 100 m in 9.231 s. The thrust of the engine is 1,500 N. What is the power of the car? Power Output
A block of mass 6 kg is moving at 4 m/s across a rough, horizontal surface. A constant frictional force acts on the block bringing it to rest over a distance of 6.51 m. What is the coefficient of friction on the block? Coefficient of Friction
A 654-kg baby elephant is charging toward you at 6 m/s. What is the kinetic energy? Kinetic Energy
A 3-kg rocket accelerates from rest at 2.5 m/s2 for 167.2 meters. What is its final kinetic energy? Kinetic Energy
A student of weight 600N climbs a vertical ladder 2.238m tall in a time of 8.0s. What is the power output in horsepower? (1 hp = 746 W) Horsepower
I launch a 0.25 kg ball bearing from a spring launcher with a spring constant of 6359.2 N/m. If the exit velocity of the ball is 20 m/s, how far did I compress the spring? Spring Compression
A rock of mass 3 kg is dropped from the top of a building 35 m tall. As it falls, it experiences air resistance. Right before impact, the rock is traveling at a speed of 23.0575 m/s. What is the percentage of energy lost due to air resistance? % Heat Loss
A car of mass 1200 kg, accelerates from 10 m/s to 30 m/s. It travels a distance of 382.775 m during this process. What is the average force that car feels from the engine during this time? Force
A bungee jumper (m=85 kg) starts 80 m above the ground and jumps off. She falls until stopped 20 m above the ground. The bungee cord is originally 52.157 m long before being stretched out. What is the spring constant of the bungee cord? Spring Constant
A 15.625-kg cannon ball is launched upwards at 15 m/s. How much kinetic energy does it have 10 meters above its launch height? (Assume no air resistance and use g = 9.81 m/s2) Kinetic Energy
A bird of mass 15 kg is flying at a speed of 25 m/s at a height of 78.6565 m above the ground. What is the total energy of the bird? Total Energy
A car smashes into a crash barrier and imparts a constant force of 40,625 N while it compresses from 4.7 m to 4.3 m. How much energy was dissipated? Work-Energy
A 75-kg cliff diver is 25 meters above the surface of the water. What is the speed of the diver at the bottom if she loses 71.7184% of her energy to air resistance? Final velocity
An elevator is being lifted up by an engine putting out a power of 20,000 W. The elevator raises a distance of 20 m in 6.05366 seconds. The elevator is 500 kg by itself and contains 2 people on this trip. How much is the combined mass of both people? Mass
What is the elastic potential energy stored in a giant slingshot ride with a spring constant of 163.5 N/m when stretched back from its resting length of 5 m to a stretched length of 17 m? Elastic Potential Energy
