An object of mass 10 kg is released at point a, slides to the bottom of the 30o incline, then collides with a horizontal massless spring, compressing it a maximum distance of 0.75 m. the spring constant is 550 n/m, the height of the incline is 2.0 m, and the horizontal surface is frictionless. round all answers to one decimal place.

11. you want to calculate the displacement of an object thrown over a bridge. using -10 m/s2 for acceleration due to gravity, what would be the total displacement of the object if it took 8 seconds before hitting the water?

In positive numbers less than 1, the zeros between the decimal point and a non-zero number are blank significant

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.
