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?

Calculate the minimum energy required to remove one proton from the nucleus 126c. this is called the proton-removal energy. (hint: find the difference between the mass of a 126c nucleus and the mass of a proton plus the mass of the nucleus formed when a proton is removed from 126c.) express your answer with the appropriate units. emin e m i n = nothing nothing request answer part b how does the proton-removal energy for 126c compare to the binding energy per nucleon for 126c, calculated using eb=(zmh+nmn−azm)c2?
