9. A helicopter is initially traveling East at 11.0 m/s. It undergoes an upward acceleration of 0.96 m/s2 up for 5.3 s. a. Draw a picture of this situation and draw the 1st kinematic vector equation (for displacement) on top of your picture. Label everything symbolically. b. What is the helicopter's displacement in component form? c. What is the helicopter's displacement in magnitude and direction form? 10. A gray kangaroo can bound across a flat stretch of ground with each jump carrying it 10 m from the takeoff point. The kangaroo leaves the ground at a 20° angle. The acceleration of the kangaroo during its jump is 9.8 m/s2 down due to gravity. b. a. Draw a picture of this situation and then draw the 1st kinematic vector equation (for displacement) on top of your picture. Label everything symbolically. Symbolically find the time it takes for the kangaroo to make this jump. (Hint: Your drawing for part a should show a right triangle. What happens if you take the tangent?) c. Plug numbers in to your answer for part b. How long does it take the kangaroo to make this jump? d. What is the kangaroo's takeoff speed? e. What is the kangaroo's horizontal speed? 11. In 1780, in what is now referred to as "Brady's Leap," Captain Sam Brady of the U.S. Continental Army escaped certain death from his enemies by running horizontally off the edge of the cliff above Ohio's Cuyahoga River, which is confined at that spot to a gorre. He landed safely on the far side of the river. It was reported that he leapt 22 ft in run about 12 m/s.
