You fall off a building that is 11.8 meters tall. How fast in meters per second will you hit the trampoline that is conveniently placed at ground level?

Which of the following is an example of units for speed

Photoelectrons with a maximum speed of 6.50 x 107 m/s are ejected from a surface in the presence of light with a frequency of 6.75 x 1014hz. if the mass of an electron is 9.10 x 10-31 kg, calculate in joules the maximum kinetic energy of a single electron. 3.84 x 10-15 j 1.92 x 10-15 j 5.92 x 10-23 j 3.07 x 10-16 j

1.what is where an object is located 2. what is how fast an objects speed is changing 3. what is how fast an object is moving
