Question

You have a ball of unknown mass, a spring with spring constant 950 N/m, and a meter stick. You use various compressions of the spring to launch the ball vertically, and then use the meter stick to measure the ball's maximum height above the launch point. Your data are as follows:

Compression, ?s(cm) Height, y(cm) 2.0 32 3.0 65 4.0 115 5.0 189

You have a ball of unknown mass, a spring with spring constant 950 N/m, and a meter stick. You use various compressions of the spring to launch the ball vertically, and then use the meter stick to measure the ball's maximum height above the launch point. Your data are as follows: Graphing either y versus (?s)2 or (?s)2 versus y gives a straight line. In the graph shown above, we chose to plot y on the vertical axis and (?s)2 on the horizontal axis because the energy conservation equation gives height as a function of compression squared. From the equation for the line of best fit given, determine the ball's mass m. Express your answer to two significant figures and include the appropriate units.

Explanation / Answer

on conserving work done=energy provided

mgh=1/2k*dels^2;

so, h/dels=slope=1/2*k/m/g=7.49*100 m^-1

using this equation=m=15.4688 kg (by putting other values of the variable)

If found any other doubt comment on my answer
