A 11 kg box slides 4.2 m down a frictionless ramp and then collides with a spring whose spring constant is 250 N/m. What is the maximum compression of the spring? I got 1.35 m but it is incorrect. Any help would be great!

1) Two boxes are placed are placed side by side on a frictionless surface so that they touch each other. Box A has a mass of 4 kg. Box B has a mass of 12 kg. A constant force of 24 N is applied to box A. What force does box A exert on box B?

How do I approach this problem? Seven green marbles and three red marbles are randomly placed in Box A and in Box B. Box A holds 4 marbles, while Box B holds 6. What is the probability that Box A has at least 2 green marbles?

A block of mass m = 3.20kg slides from rest a distance d down a frictionless incline at angle θ = 30.0° where it runs into a spring of spring constant 425 N/m. When the block momentarily stops, it has compressed the spring by 22.0 cm. (a) What is the distance d? I found ...

the weight of 4 boxes together is 66.5kg.the weight of box B is 2kg less than box A.and the weight of box C is 1.5kg more than box A.if the weight of box D is 1.5kg more than box C.find the weight of each box

A box is given a push so that it slides across the floor. How far will it go, given the coefficient of kinetic friction is .21 and the push imparts an inital speed of 4.2 m/s?
