1)A ball is thrown at 29° below the horizontal from a rooftop of height 95 m. It lands 2.4 s later. Find: Find:
[url removed, login to view] initial speed
[url removed, login to view] point of impact with the ground( m from the base of the building)
[url removed, login to view] angle at which it hits the ground.( ° below the horizontal )
2)A geosynchronous satellite is one that appears to be fixed in the sky, a condition useful for telecommunications. If such a satellite orbits the earth at an altitude of 47500 km above the earth's surface, what is its centripetal acceleration? The radius of the Earth is about 6370 km.
3)A plane dives at 26° to the horizontal and releases a package at an altitude of 500 m. If the load is in the air for 4.2 s, find:
a. the speed of the plane when it released the package;
b. the horizontal distance traveled by the package after it is released.
4) An electron in an atom has a speed of 2.5×10^6 m/s and orbits the nucleus at a distance of 5.4×10^-11 m. What is its centripetal acceleration?
