Unformatted text preview: c) Calculate the magnitude and direction of the displacement vector. 3 3. A projectile is thrown from the edge of a building with an initial speed of 65.0 m/s at an angle of 37 o with the horizontal. The height of the building is 150 m. See figure below. (10 pts) h = 150 m 37 o 65 m/s V o = X a) Calculate the time for the projectile to strike the ground. b) Calculate the range X of the projectile. 4 4. A clock has a second hand of length 20 cm. From the 12 P.M mark to the 9 P.M mark, for the tip of the second hand, : a) Calculate the displacement vector in unitvector notation. b) Calculate the average velocity vector in unitvector notation. c) Calculate the period of rotation. d) Calculate the speed. e) Calculate the instantaneous acceleration vector in unitvector notation as it passes through the 6 P.M mark. f) Calculate the average acceleration vector in unitvector notation....
