is the mass of the Earth, and m. is the mass of an object on the surface of the Earth. This force is exactly the same force that gives the pendulum its weight: F = mg. If we equate the two, we find that the mass of the object cancels. We then do some additional algebraic manipulation to solve for the mass of the Earth and get our equation in ...

The equation for momentum is abbreviated like this: p=m×v. Momentum, symbolized with a p, is expressed in units of kg·m/sec; m is the mass of the object, in kilograms; and v is the velocity of the object in m/sec. Use your knowledge about solving equations to work out the following problems. Be sure to show all your work with units:

Calculate the magnitude of the force exerted by the spring on the cart, as a function of the mass of the hanging object, the mass of the cart, and the angle of the track. For data analysis, it will be useful to calculate the amount the spring stretches, rather than the force exerted on the spring, so write an equation for the spring stretch as ...
