Hi there!

I have no idea what is the answer to this and I think it's the elements that are throwing me off.

If you could help that would be absolutely amazing. Thank you!

What is the momentum of a 2 kg object moving at 15 meters per second

Calculate the first and second velocities of the car with four washers attached to the pulley, using the formulas v1 = 0.25 m / t1 , and v2 = 0.25 m / (t2 – t1) where t1 and t2 are the average times the car took to reach the 0.25 and the 0.50 meter marks. record these velocities, to two decimal places, in table e.

The ability to make things happen is also called a. heat b. force c. matter d. energy
