What force is required to keep a 245kg wood pallet moving at a constant speed across a concrete floor

This equation represents Newton's Second Law of Motion, F=ma. It shows the relationship of force, mass, and acceleration.

If you throw a ball upward with an initial speed of 4m/s at 1.5m above the ground, find a. the flying time for this free fall motion, b. the final velocity just before touching the ground, and c. the maximum height with respect to the ground.

Objects 1 and 2 attract each other with a gravitational force of 72.0 units. If the distance separating Objects 1 and 2 is changed to one-third the original value, then the new gravitational force will be units

If a 1000-pound capsule weighs only 165 pounds on the moon, how much work is done in propelling this capsule out of the moon's gravitational field? (Note: The radius of the moon is roughly 1080 miles)

Which particles make up the nucleus of an atom? A. protons and electrons B. neutrons and electrons protons only protons and neutrons E. neutrons only

Place the ball in the plastic bag, and twist the top so the ball is secure in the bag. Wrap the twisted portion with tape so it stays tight. Use the hole punch or scissors to poke a hole in the part of the bag that's above the ball.

What does a fern ultimately depend on as an energy source?

According to the Doppler Effect, which statement is true about a sound as it approaches you and then moves away. A) As the source approaches you, the sound waves are compressed so the pitch of the noise increases.

If you have a beam perfectly balanced on a fulcrum and put a weight at the very end of one side, is there a way to know where you should put a heavier object on the other end?
