You are going to throw a ball upward at an angle of 19.03 degrees. If you can throw it with an initial speed of 7.0 m/s, what is its initial horizontal velocity component? Your Answer:

A projectile is fired from the ground, reaches a maximum height of 40.4 m and lands a distance of 22.9 m away from the launch point. What was the projectile s launch velocity? 28.2 m/s, 41.0 degrees above horizontal 4.0 m/s, 41.0 degrees above horizontal 51.1 m/s, 20.5 degrees above horizontal 28.4 m/s, 81.9 degrees above horizontal

A football is kicked from ground level with an initial velocity of 24.6 m/s at angle of 47.5° above the horizontal. How long, in seconds, is the football in the air before it hits the ground? Ignore air resistance.

In an article on the use of the sling as a weapon, the author states that a skilled slinger can sling a rock a distance of about 384 m. What is the minimum speed the rock must have when it leaves the sling to travel exactly 384 m? To solve this problem it will be necessary to first determine the required launch angle of the projectile. What launch angle must the projectile have in order to find the minimum speed required to achieve a given horizontal distance?
