1. Calculate the energy transferred into/out of the system based on your data (a graph is a good way to visualize this calculation). Is this consistent with the acceleration of friction measurements you collected in Lab 3? Explain.
2. Evaluate the Law of Conservation of Energy (as given in the intro of this lab manual) in light of your group's data and analysis. Be as specific as possible in highlighting any deficiencies you see in the Law or in your data.
Which two particles that make up atoms have about the same mass? Which two have the same magnitude of electric charge? What is an electric current, and what are its units? (Give two equivalent units.)
How far apart do the end up? In which direction is Hiker 2 relative to Hiker 1?

A 5.00 kg object moving to the right with a speed of 20.0 cm/s makes an elastic head-on collision with a 10.0 g object initially at rest. Find the velocity of each object after the collision
A tire 2.0 ft in diameter is placed on a balancing machinewhere it is spun so that its tread is moving at a constant speed of59 mph. What is the acceleration of the stone as the tire is being balanced
A football is kicked with an initial speed of 10.2 m/s at an angle of 40.00 above the horizontal. It lands on the ground 2.12 s later. Determine the velocity of the football at the pinnacle of its trajectory.
The surface charge density on an infinite sheet is -2.0 x 10-6 coulomb. How far does the particle travel before reaching its truning point
The earth's radius is 6.37×106m; it rotates once every 24 hours. What is the earth's angular speed? Viewed from a point above the North Pole, is the angular velocity negative and positive? What is the speed of a point on the equator?
A particle falls to Earth starting from rest at a great height(many times Earth's radius). Neglect air resistance and show thatthe particle requires approximately 9/11 of the total time of fallto traverse the first half of the distance. [Note: You wi..
