a body is thrown vertically upward from the Earth's surface and it took 8 seconds to return to it's original position. find out the initial velocity with which it was throw up ( The air resistance is considered as zero)​

Which quantities are scalars? choose all that apply a.distance b.speed c. acceleration d.velocity

Astate of matter all that has define volume and can flow is a(n)

Choose a realistic problem for which these are the correct freebody diagrams. be sure that the answer that the problem requests is consistent with the diagrams shown. choose a realistic problem for which these are the correct freebody diagrams. be sure that the answer that the problem requests is consistent with the diagrams shown. a 1.0 kg block is placed on top of a 2.0 kg block. a horizontal rope pulls the 2.0 kg block across a frictionless floor with a force of 21.0 n. the coefficient between the two blocks is 0.75. does the 1.0 kg block on top slide?
