(8th grade HELP) 1. Inertia causes a stationary object to...
a. stay still
b. move
c. have an increased velocity
d. change it’s speed or direction
2. Once an applied force causes an object to start moving, the object keeps moving because
a. none of the above
b. the force continues to be applied to it
c. no other force is acting on it
d. it has inertia

(1 point) match the differential equations and their vector valued function solutions. you may wish to multiply at least one solution out fully, to make sure that you know how to do it. you can get the other answers quickly by process of elimination and just multiply out one row element.

Give an example in which the electrical energy changes to light energy

Aspring is used to stop a 50-kg package which is moving down a 20º incline. the spring has a constant k = 30 kn/m and is held by cables so that it is initially compressed 50 mm. knowing that the velocity of the package is 2 m/s when it is 8 m from the spring and neglecting friction, determine the maximum additional deformation of the spring in bringing the package to rest.
