At a top of a building, a projectile is launched with an initial velocity of 25.0m/s at an angle of 30° above the horizontal. It takes the projectile t = 3.96s from launch to hit the ground, C. What is the horizontal range from the base of the building to the point where the projectile strikes the ground?

A projectile is launched from a 20.0 m high cliff with an initial velocity of 28.0 m/s at an angle of 35.0° elevation.  What is the maximum height above the ground (at the bottom of the cliff) the projectile will go?

A projectile is thrown from the top of a cliff with an initial speed of 25 m/s at an angle of 600 up from the horizontal. If the projectile lands 100 m from the base of the cliff how tall is the cliff?

To start an avalanche on a mountain slope, an artillery shell is fired with an initial velocity of 330 m/s at 46.0° above the horizontal. It explodes on the mountainside 40.0 s after firing. What are the x and y coordinates of the shell where it explodes, relative to its firing point?

A batter hits the baseball A with an initial velocity of vo = 91 ft/sec directly toward fielder B at an angle of 38° to the horizontal; the initial position of the ball is 2.4 ft above ground level. Fielder B requires 0.24 sec to judge where the ball should be caught and begins moving to that position with constant speed. Because of great experience, fielder B chooses his running speed so that he arrives at the "catch position" simultaneously with the baseball. The catch position is the field location at which the ball altitude is 7.9 ft. Determine the velocity of the ball relative to the fielder at the instant the catch is made. Vo 438° 2.4' Answer: VA/B = (i 204' B i+ i Next question j) ft/sec

A golfer hits an approach shot with a velocity of 38.2 m/s at 50 degrees above the horizontal. The golf ball lands directly next to the hole, 5.50 m above the ball’s original position, and stops immediately. How far horizontally was the golfer from the hole?

The initial speed of the ball is v0 = 22.2 m/s, the angle the ball is hit at is θ = 43o, and g = 8.4.   How far away does the ball hit the ground?

An artillery shell is fired with an initial velocity of 300 m/s at 59.0° above the horizontal. To clear an avalanche, it explodes on a mountainside 46.0 s after firing. What are the x- and y-coordinates of the shell where it explodes, relative to its firing point?

what’s the initial and final height of the ball?

You hit a golf ball from the (level) ground, with an initial speed and an initial angle.  Ignore air resistance.  (This is very unrealistic.) The initial speed is v0 = 23.7 m/s, and the angle the ball is hit at is θ = 46o.  Calculate vx0, the initial horizontal component of velocity (in m/s). What equations describe the trajectory of the golf ball?
