What are the answers on science homework?
I just finished and would like to check my answers.
Find the kinetic energy of a 0.1-kilogram toy truck moving at a speed of 1.1 meters per second.
What is the speed of a 48-kilogram dog running across a lawn with 216 joules of kinetic energy?
A book on a shelf 2.0 meters above the floor has a mass of 1.5 kilograms. What is the gravitational potentialenergy of the book?
Find the mass of a ball on a roof 30 meters high, if the ball’s gravitational potential energy is 58.8 joules.
Which runner has greater kinetic energy: a 46-kilogram runner moving at a speed of 8 meters per second or a 92-kilogram runner moving at a speed of 4 meters per second?
If a 6.0-kilogram box is moved from the floor to a storage compartment 2.0 meters above the floor, by how many joules does its gravitational potential energy change?
A 0.1-kilogram ball rolls across the floor at a speed of 2 meters per second. Another 0.1-kilogram ball rests ona shelf 1 meter above the floor. Which ball has more energy?
Thank you some much your i will be forever thankful
