1. A strange high school teacher is dropping golf balls from a flight of stairs. The second dropped ball takes 3 times longer to hit the ground. The first ball falls 4 meters. Both are dropped from rest. a. Calculate the time it takes the first ball to drop 4 meters. b. What is the landing speed of the second ball? c. From what height was the second ball dropped? 2. The incline here is of an angle of 15 degrees. The coefficient of static friction is 0.25 and the coefficient of kinetic friction is 0.11. Calculate the acceleration of the block if it starts from rest. Mass equals 3-kg. 0 3. A particular bowling ball weighs 14 pounds on our Earth's surface right now. If this ball is placed on a planet that is twice the mass of Earth and twice the radius of Earth, then how much would it weigh there? Mass of Earth = 5.972 x 1024 kilograms, Radius of Earth = 3959 miles 4. A geosynchronous satellite orbits MARS which rotates at 1 day and 37 minutes. This allows the rovers to be in constant radio contact. The mass of Mars is 6.42 x 1023 kilograms and it has a diameter of 6787 kilometers. How far above the surface of Mars do the engineers need to place this satellite to maintain this orbit? Remember: the force of gravitational attraction supplies the centripetal force for the satellite. G= 0.0000000000667 = 6.67E-11 1.
