A projectile is fired at an angle of 55.0° above the horizontal with an initial speed of 35.0 m/s. 17. What is the magnitude of the horizontal component of the projectile's displacement at the end of 2 s? Ans: 40 m 18. How long does it take the projectile to reach the highest point in its trajectory? Ans: 2.9 s Use the following to answer questions 19-21. A shell is fired with a horizontal velocity in the positive x direction from the top of an 80-m high cliff. The shell strikes the ground 1330 m from the base of the cliff. The drawing is not to scale. 80 m - 1330 m 19. Determine the initial speed of the shell.
