Question

Prolab: 1. A 4.0m long board is supported one meter from each end as shown. The mass of the board is 10kg. A 2kg ball is rolled slowly from the left edge of the board to the right edge of the board. On the axes below. prepare a graph of the force that must be provided by the left support and a graph of the force that must be provided by the right support as the ball travels the 4m. Note: use a solid line for the force on the loft support and a dashed line for the force on the right support. Show work to support your graph.

Explanation / Answer

in this problem we need find moment on right and left ends

(mass of board+ball)*9.8*1=mass of board*9.8*x

distance=1.2m
