Do you launch a projectile at an initial speed of 63.5 m/s from the ground. After 8.40 seconds of flight, the projectile lines on the ground. At what angle above the horizontal was the projectile launched?

A projectile is fired horizontally from the height 14 m and hits a target 15.7 m away in the conventional x-direction. What was the initial speed of the projectile?

A projectile is fired with an initial speed of 37.6 m/s at an angle of 42.9 above the horizontal on a long flat firing range. Determine the maximum height reached by the projectile. Express your answer using three significant figures and include the appropriate units.

You launch a projectile at an initial speed of 46.3 m/s from the ground. After 6.40 seconds of flight, the projectile lands on the ground. At what angle above the horizontal was the projectile launched?     32.8 degrees     38.5 degrees     42.7 degrees     76.9 degrees

Dr. Strange throws a ball to Dr. Evil with a speed of 9.60m/s at an angle of 41.00 above the horizontal, from an initial height of 1.95m above the ground. Dr. Evil catches the ball at a height of 0.63m above the ground. How far horizontally from Dr. Strange is Dr. Evil standing?

An archer fires an arrow at a target that is a horizontal distance d = 55 m away; the bull’s-eye of the target is at same height as the release height of the arrow.  1. At what angle, in degrees above the horizontal, must the arrow be released to hit the bull’s-eye if the arrow's initial speed is 35 m/s?

A projectile was fired at an angle of 30.0° above the horizontal with an initial speed of 20 m/s. The same projectile was fired a second time with the sane initial speed of  20 m/s but at a different angle such that the height attained by the projectile in the second launch is one half of the horizontal distance covered by the projectile in the first launch. At what angle was the projectile launched second time?

You launch a projectile at an initial speed of 30.9 m/s from the ground. After 3.40 seconds of flight, the projectile lands on the ground. At what angle above the horizontal was the projectile launched?     24.6 degrees     32.7 degrees     49.1 degrees     21.8 degrees

A football is kicked by a football player. It's initial trajectory is at an angle of ø = 50° above the horizon and has a speed of u = 45 m s-1. The ball lands away from the initial position at a location 7.5m higher from where it was originally kicked. If air resistance is neglected and gravity is taken to be 9.8 m s-2, what is the magnitude and direction of the velocity of the football at the instant it lands?

A hunter spots a duck flying a given distance, h, above the ground (in meters) and shoots at it with his shotgun.  The buckshot leaves the shotgun at an angle equal to 57.7 degrees from the horizontal with a velocity of 105 m/s.  The duck is flying at a speed of 30 m/s in a horizontal direction toward the hunter.  If the hunter shot when the duck was 200 meters away from the hunter and hit the duck, how high was the duck flying?
