A 1.2 kg block slides along a frictionless surface at 1.2 m/s. a second block, sliding at a faster 4.4 m/s, collides with the first from behind and sticks to it. the final velocity of the combined blocks is 3.2 m/s.

A pebble is dropped from a cliff. Neglecting air resistance, if the rock falls for 4 seconds. How fast is it moving?

The work of Subrahmanyan Chandrasekhar is likely to have been most influenced by the work of which of the following scientists? A. Albert Einstein B. Edwin Hubble C. Marie Sklodowska-Curie D. Lord Kelvin

Why can making observations be a very good way to come up with a scientific question?

Two blocks, stacked one on top of the other, slide on a frictionless horizontal surface. The surface between the two blocks is rough, however, with a coefficient of static friction equal to 0.50. The top block has a mass of 2.
