Erica and Jim are given a closed container of ice. They find the mass of the container and ice to be 28.0 grams. The container of ice is left on the lab table overnight. The next day, Erica and Jim observed the container. All of the ice had melted. They place the
container back on the balance and found the mass to be
A)
the same as it was the day before.
B)
more than it was since the ice had melted.
more than it was since a new compound was formed.
D)
less than it was since the container was fill of liquid.

An automobile of mass 2000 kg moving at 30 m/s is braked suddenly with a constant braking force of 10000 n. how far does the car travel before stopping?

Aball is thrown straight up into the air with a speed of 21 m/s. if the ball has a mass of 0.1 kg, how high does the ball go? acceleration due to gravity is g = 9.8 m/s^2. a. 22.5 m b. 20.0 m c. 25.0 m d. 17.5 m

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?
