Mary and her sister are playing with a cardboard box on the neighborhood hill. Mary climbs into the box, the total mass of the box with Mary in it is 115 kg. The box starts at rest at the beginning of the incline. The hill is at an incline of 28 degrees with respect to the horizontal.The static and kinectic friction between the box and hill is 0.4 and 0.2 respectively. Assume the box is sliding downhill. a. What is the magnitude of the acceleration of the box? (same as Problem 3b)b. If the hill is 5m tall, what is the Mary's speed when she reaches the bottom?c. At the bottom of the hill, the ground becomes level, but the coefficients offriction do not change. How far will Mary slide before she comes to a stop?
5. A box with a mass of 100 kg was originally attached to the spring at position A. After that, pressure was applied to the box until The spring compresses to a distance of X - 1 m and releases it, causing the box to move upwards along the inclined floor. If the incline has and = the coefficient of friction uk = 0.3, find the box that can travel along the incline for a maximum distance in meters.
