A kangaroo can jump to a maximum height of 8m when it leaves the ground at 450. With what speed must the kangaroo leave the ground to reach that height? A 15.34 mis B 10.84 m/s 58.8 m/s D 12.90 m/s Question 12 4 Points A projectile is fired horizontally with an initial speed of 47 m/s. What are the horizontal and vertical components of its displacement 2.0 s after it is fired? A) x = 23.5m y = 74.4m x = 94.0m y= - 19.6 m x = 94.0 m y = 19.6 m (D x = 23.5 m y= - 74.4m Question 13 4 Points A projectile is fired horizontally with an initial speed of 47 m/s. What are the horizontal and vertical components of its velocity 2.0 s after it is fired? A Vx = 47 m/s vy = 19.6 m/s B Vx = 23.5 m/s vy = -19.6 m/s C Vx = 47 m/s Vy =-19.6 m/s D Vx = 23.5 m/'s Vy = 19.6 m/s
