In an action movie, the villain is rescued from the ocean by grabbing onto the ladder hanging from a helicopter. he is so intent on gripping the ladder that he lets go of his briefcase of counterfeit money when he is 130 m above the water. if the briefcase hits the water 6.0 s later, what was the speed at which the helicopter was ascending?

You've already seen the value of 9.8 in this lesson. what's this value called? what quantity does it represent?

Asatellite that goes around the earth once every 24 hours iscalled a geosynchronous satellite. if a geosynchronoussatellite is in an equatorial orbit, its position appearsstationary with respect to a ground station, and it is known as ageostationary satellite find the radius rof the orbit of a geosynchronous satellite that circles the earth.(note that ris measured from the center of the earth, not the surface.) you mayuse the following constants: the universal gravitational constant g is 6.67 \times 10^{-11}\; {\rm n \; m^2 / kg^2}. the mass of the earth is 5.98 \times 10^{24}\; {\rm kg}. the radius of the earth is 6.38 \times 10^{6}\; {\rm m}.

What are the differences and relationships between speed, velocity, and acceleration
