Question 1 - Dinàmica de Newton i forces · Física I URV 2023

A crate of mass $m = 20\text{ kg}$ is pulled up a ramp inclined at an angle of $30^\circ$ with respect to the horizontal to reach an elevation of $h = 3\text{ m}$. The pulling force is applied via a rope with a tension of $F = 200\text{ N}$ forming an angle of $45^\circ$ above the incline surface. The kinetic friction coefficient between the crate and the plane is $\mu_k = 0.2$. (Take $g = 9.8\text{ m/s}^2$).

a)

Calculate the acceleration of the crate up the ramp. [2.5 points]
