What average net force is required to stop a 4.5 kg bowling ball, initially at rest, accelerated for 6 seconds over a distance of 3m

a.) is the correct answer.

explanation:

that would be because of both gravity and friction. so     c

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
