1. On their way through Grand Bahama Island, the eye of a hurricane is moving in a direction 61.0 ° north of west at a speed of 41.4 km / h. Three hours later, during the hurricane suddenly shifts to the north, and speed drops to 26.6 km / h. How far from Grand Bahama is the eye 4.40 h after passing through the island? ? km 2. That the land on an unknown planet somewhere in the universe, which clearly has weaker gravity than Earth. To measure g on this planet to do the following experiment: A ball is thrown upward from the ground. It passes a window 14.0 m above the ground and is going through the same window 2.00 s after they spent their way up. It reaches the ground again after 5.00 s it was launched. Calculate the magnitude of g (acceleration of gravity) on the surface of this planet. g =?? m/s2
1 – Draw the box and make the shot. = Angle of 61 degrees Hypotenuse = 41.4 cos 61 = x/41.4 x = 20.07 km / h = 61 y/41.1 sin y = 36.21 km / h. After 3 hours: 3 * 7.20 = 60.21 GBI km north of 3 * 36.21 = 108.63 km west og GBI then heads north from 4.4 to 3 = 1.4 * 6.26 = 37.24 04.01 kilometers hours@26.6 final position to North: x = 108.63 + 0 = 108.63 km west of the GBI y = 60.21 + 37.24 = 97.45 km north of GBI Tan ^ 1 = 97.45/108.63 = 0.897 angle = 41.9 degrees north west (311.9 degrees of the compass) 97.45 Magnitude = 41.9 sin / d = 0.668 = 145.88 km 145.88 km 97.45/dd hurricane is the northeast of GIB in a delay of 311.9 degrees I have to run. Good luck with # 2. Just crank through Newton's laws of motion
