Ti Bon TI 7) A boomerang is thrown by a person in the open space, the person observes its journey in the air for an elapsed time of 2.5 seconds. Its initial "7" and final position "77" of observation are: 7 = 5.00 m i +7.00 mj + 3.00 m k; and = -2.00 mi-6.50 m j + 4.00 m k What is the average velocity with which the boomerang has travelled during elapsed time of observation.
8) In a natural disaster hit area, the government starts distributing essential supplies by dropping them in small packages from a moving helicopter at the open spaces. The helicopter is moving with a constant speed of 40 miles/hr over an altitude of 300 m above the ground when the package is dropped from the helicopter. A) What is the time "t" taken by the package to go from the helicopter to the ground? B) What is the horizontal distance "d" covered by the package from the point of being dropped from the helicopter to the point of reaching the ground? y-axis Vox = 40 miles/hr Yo Voy = 0 300 m 0 x x-axis
