two city buses are traveling at 24 mph the buses are the same model and year one bus has 30 passengers. the other bus has twelve which is the best prediction
the buses kinetic energies will depend on their routes
the buses will have the same amount of kinetic energy
the bus with 30 passengers will have less kinetic energy
the bus with 12 passengers will have less kinetic energy
4 answers
the bus with 12 passengers will have less kinetic energy
1. What does an object's kinetic energy depend on?
its mass and speed
2. Two city buses are traveling at 24 miles per hour. The buses are the same model and year. One bus has 30 passengers. The other bus has 12 passengers. Which is the best prediction?
The bus with 12 passengers will have less kinetic energy.
3. A softball player hits a ball at 78 miles per hour. Then she hits a ball at 80 miles per hour. Which is the best prediction?
The ball hit at 80 miles per hour will have more kinetic energy.
4. A hawk is chasing a sparrow. At the beginning of the chase, the hawk's kinetic energy is 5.1 Joules. At the end of the chase, the hawk doubles its speed. What is the best prediction for its kinetic energy at the end of the chase?
20.4 J
5. A student rolls two marbles down an inclined plane. One marble has a mass of 4.8 grams. The student calculates its kinetic energy to be 0.0035 Joules when it reaches the end of the plane. The second marble has a mass of 2.4 grams. What is the best prediction for its kinetic energy at the end of the plane?
0.00175 J
