1. A box (mass m = 20 kg) is
placed on a slope (LaTeX: \thetaθ = 40°), as shown in the diagram
below. The coefficients of friction between the box and the slope
are LaTeX: \muμs = 0.6 and LaTeX: \muμk = 0.4. The box is released
from rest on the slope.
Determine the acceleration of the box after it is released.

U Question 4 2 pts Problem 3: Proton travelling inside a parallel-plate capacitor. A proton travelling at a speed of 1.0 x 106m/s enters the gap between the plates of a parallel-plate capacitor. The plates are 2.0 cm long in the direction the proton is travelling and the surface charge densities on the plates are 1.0 x 10C/m². Assume the electric field is uniform inside the capacitor and zero outside. The mass of a proton is 1.7 x 10-27 kg....
