Input your answer in m/s and with 1 decimal places. 5 points Save Answer QUESTION 8 An arrow is shot from a height of 8.8 m toward a cliff of height H. It is shot with a velocity of 31.8 m/s at an angle of 360 above the horizontal. It lands on the top edge of the cliff 3.1 s later. What is the height of the cliff? Input your answer in meters using 3 significant figures. (g = -9.80 m/s2) 10 points Save AnswerQUESTION 3 An eagle is flying horizontally at a speed V over a lake at a height H when the fish in its claws break free and fall into the lake. What is the speed of the fish relative to the water at the moment it hits the water? OV+ 28H, where g = 9.80 m/s2 O V2 - 28H, where g =9.80 m/s2 O V2 + 28H, where 8 =9.80 m/s2 O V2 + 28H, where g = - 9.80 m/s2 5 points Save AnswerQUESTION 4 An projectile is kicked from the ground level with an initial velocity Vx in the horizontal direction and Vy in the vertical direction. At what speed does the projectile hit the ground? 0 V2+V2 x ,- 0v, 5 points Save Answer QUESTION 5 An object is thrown horizontally from the top of a 15-m building and lands 45 m from the base of the building. Ignore air resistance. How long is the ball in the air? Input your answer in seconds using 3 signicant figures. (9 = -9.80 m/sz) : QUESTION 1 An eagle is flying horizontally at a speed of 1.64 m/s when the fish in her talons wiggles loose and falls into the lake 7.10 m below. Calculate the velocity of the fish relative to the water when it hits the water. Input your answer in m/s using 3 significant figures. (g = -9.80 m/s?) 5 points Save Answer QUESTION 2 An arrow is shot from a height h toward a cliff. It is shot with a velocity V at an angle of @ above the horizontal. It lands on the top edge of the cliff time t later. What is the height of the cliff? Oh + t V cose - 812/2, where g = 9.80 m/s2 Oh + tV sino - 812/2, where g = -9.80 m/s2 Oh+ tV sin+ 812/2, where g = 9.80 m/s2 Oh + tV sino - 812/2, where g = 9.80 m/s2 10 points Save AnswerQUESTION 12 An projectile is kicked from the ground level with an initial velocity of 14 m/s in the horizontal direction and 30 m/s in the vertical direction.
