4. You are pushing horizontally with a 300 N force on a box that is on an inclined plane as shown. The mass of the box is 30 kg and the incline is at a 25 degree angle off the Fapplied horizontal. The coefficient of kinetic friction between the box and the incline is 0.3, and the coefficient of static friction i 0.4. Assuming the box was at rest at t=0 when the force is initially applied, is the box moving up the ramp, down the ramp, or is it at rest after the force has been applied? 25⁰

Problem Find the particle's horizontal position x(t) and velocity v(x) at any point in a fluid whose drag force is expressed as Fdrag = kmv where, k is a constant, m is the mass of the particle and v is its velocity. Consider that the particle is initially traveling with a velocity v0. Solution: a) To solve for the position as a function of time x(t), we construct the net force in the x-axis as ∑F = -F_____ = m_____ Then: -m_____v = m_____ since: a = dv/dt then -m_____v = m_____ by integrating, we obtain the following expression: _____ = v0e_____ Further, employing the rules of integration results to the following expression for position as a function of time x= (v0/_____)( _____ - e _____ ) as t -> ∞ , the position becomes x = v0/k b) To solve for the velocity as a function of position v(x), we construct the net force in the x-axis as follows ∑F = -F _____= m_____ Then: -m_____v = m_____ since: a = dv/dt then -m_____v = m_____ We can eliminate time by expressing, the velocity…
