From the position-time graph, create a velocity-time graph. Or simply fill in the rest of the data table (calculate change in position over change in time = velocity). Make sure all graphs are clearly labeled, show appropriate scales on the axes, and have titles. Connect the points with an appropriate line of best fit (straight or curved).

The change in momentum is mΔv where m is the mass of the object and Δv is its change in velocity. Momentum is the product of mass times velocity or mv. This equation describes a powerful relationship that lets us predict the motion of an object. Use your equation to predict the impulse applied to the cart if the change in velocity was 2.5 m/s.

p = m*v where P is momentum, m is mass, and v is the velocity right before the ball hits the surface. p = 0.0058 kg * 4.43 m/s. p = 0.0257 kg * m/s. Calculate the momentum of each ball after it hits the surface (Ending Momentum). Tennis Ball: p is momentum, m is mass, and v is the velocity right after the ball hits the surface Surface 1: p = m*v
