8. A projectile is fired from the ground, reaches a maximum height of 57.1 m and lands a distance of 52.9 m away from the launch point. What was the projectiles launch velocity? 55.0 m/s, 30.8 degrees above horizontal 34.4 m/s, 77.0 degrees above horizontal 33.5 m/s, 38.5 degrees above horizontal 7.8 m/s, 61.6 degrees above horizontal

6. A projectile is launched at ground level with an initial speed of 46.0 m/s at an angle of 35.0° above the horizontal. It strikes a target above the ground 2.70 seconds later. What are the x and y distances from where the projectile was launched to where it lands? 7. A ball is thrown horizontally from the top of a 54.0-m building and lands 117.3 m from the base of the building. Ignore air resistance. (Assume the ball is thrown in the +x direction and upward to be in the +y direction.) (a) How long (in s) is the ball in the air?  s (b) What must have been the initial horizontal component of the velocity (in m/s)? (Indicate the direction with the sign of your answer.)  m/s (c) What is the vertical component of the velocity (in m/s) just before the ball hits the ground? (Indicate the direction with the sign of your answer.)  m/s (d) What is the velocity (in m/s) (including both the horizontal and vertical components) of the ball just before it hits the ground? magnitude…
