3. A box (mass = 100 g) is initially connected to a compressed (x = 80 cm) spring (k = 100 N/m) at point A. It was released and started moving along the horizontal surface (μ = 0.2) until it moves up along the inclined surface (uk = 0.3). The box then stops at point D alone the incline. Consider that e = 30 m and 0 = 30°. (a) What is the velocity of the box at point B?) (Ans: 25.24 m/s) (b) What is the change in kinetic energy from point B to point C? (Ans.: -5.88 J) (c) What is the velocity of the box at point C? (Ans.: 22.79 m/s) (d) What is the length of the incline, f? (Ans. 34.88 m) (e) What is the change in gravitational potential energy from point A to point D? (Ans. 17.10J) www.m 0 X e A B D C
