Ahorizontal cable pulls a 200-kg cart along a horizontal track. the tension in the cable is 500n. starting from rest, how long will it take the cart to reach a speed of 8 m/s? how far will it have gone?

The harmonic motion of a particle is given by f(t) = 2 cos(3t) + 3 sin(2t), 0 ? t ? 8. (a) when is the position function decreasing? (round you

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.

Who was the first scientist to measure speed as distance over time?
