A student must determine the effect of friction on the mechanical energy of a small block as it slides up a ramp. The block is launched with an initial speed to from point A along a horizontal surface of negligible friction. It then slides up a ramp, where friction is not negligible, that is inclined at angle 0 with respect to the
horizontal, as shown in the figure. The student measures the maximum vertical height hattained by the block while on the ramp, labeled as point in the figure.
At point B, the block comes to rest. The student performs three trials with the ramp at different angles, launching the block at the same initial speed Ny for each
trial. The results from the trials are displayed in the table.
Consider the trial in which the ramp is at a 20 angle with the horizontal. The surface of the ramp has been replaced with a surface in which frictional forces are
considered to be negligible. If the mass of the block is doubled and the initial launch speed is doubled, how could the student predict the new vertical of the
block at point B?
