1. A ball is thrown horizontally from the top of a 60.0-m building and lands 100.0 m from the base of thebuilding. Ignore air resistance. (a) How long is the ball in the air? (b) What must have been the initial horizontalcomponent of the velocity? (c) what is the vertical component of the velocity just before the ball hits theground? (d) What is the velocity (including both the horizontal and vertical components) of the ball just before ithits the ground? (e) Construct a graph of the position, velocity, and acceleration of the ball from launch tolanding.

Since there are multiple sub-parts, we will answer the first three sub-parts for you. If you want…

A golfer is attempting to reach the elevated green by hitting his ball under a low-hanging branch in one tree A, but over the top of a second tree B. If the launch speed of the golf ball is v0 = 112 mi /hr, what launch angle θ will put the first impact point of the ball closest to the pin? How far from the pin (distance d) is this impact point?
A stone is thrown horizontally from the highest point of a 95 m building and lands 115 m from the base of the building. Ignore air resistance, and use a coordinate system whose origin is at the highest point of the building, with positive y upwards and positive x in the direction of the throw. How long is the stone in the air in seconds? What must have been the initial horizontal component of the velocity, in meters per second? What is the vertical component of the velocity just before the stone hits the ground, in meters per second? What is the magnitude of the velocity of the stone just before it hits the ground, in meters per second?
A locust jumps at an angle of 55.0 degrees and lands 0.820 m from where it jumped. What is the maximum height of the locust during it’s jump? Ignore air resistance. If it jumps with the same initial speed at an angle of 45.0 degrees, what is the maximum height? If it jumps with the same initial speed at an angle of 45.0 degrees, what would the range be?
A baseball batter hits his home run ball with a velocity of 110 ft/s at an angle of 45° above the horizontal. If the ball hits the top of a screen at the 300 ft mark and bounces to the crowd, how high above the ground is the top of the screen?
A kicker for an NFL team is tasked with nailing a field goal from 41m out from the goal post. The ball must clear a cross bar that is 3.1 m about the ground. If the kicker launches the ball from the ground at a launch speed of 25.8m/s and an angle of 49 above the horizontal, how high is the ball in the air when it passes the cross bar 41m away?
A football game begins with a kickoff in which the ball travels a horizontal distance of 37 m(approximately 40 yd) and lands at the same level from which it was kicked. If the ball waskicked at an angle of 44 ° above the horizontal, what was its initial speed?
In a football game, a player wants to kick the ball as far as possible, but also make sure that it stays in the air as long as possible, so that there is enough time for other players to run down the field and tackle the receiver. If the football is supposed to travel a distance of 49.8 m and stay in the air for 4.41 s, what initial angle and speed does the player have to provide? You can assume that the initial and final vertical coordinate are zero. Hint: Start from the range equation that you derived in class.
*Draw a simple diagram representation for the solution.In a game war, one team sets base on a cliff 15m high and 60m away from the opponent’s base. At what velocity must the attack be launched so that the lower base will be hit? The initial launch is at 20 degrees below the horizontal?
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?
A rugby player passes the ball 9.75 m across the field, where it is caught at the same height as it left his hand. At what angle was the ball thrown if its initial speed was 12.0 m/s, assuming that the smaller of the two possible angles was used? (Answer in Degrees) What other angle gives the same range? (Answer in Degrees) For the pass using the smaller of the two angles, how long is the ball in the air? (answer in Seconds)
A projectile is fired at the edge of a cliff, with an initial velocity of 12 m/s at an angle of 40 degrees. If it takes the projectile to 10s to land on the bottom of the cliff, how far did it travel horizontally?
the leprechaun in the shamrock patch was named O'Malley and since he was disrupted from sitting in his patch he decided to go off and play a round of his favorite sport in where leprechaun kick a gold coin from a tee into a post 317m away. if he kicked the coin at an angle of 60 degree at a velocity of 60 m/s how high was the arch of the rainbow created by the trajectory? how long did it take to get to the pot? the officials in dublin decided to add a goal post to "kick O coin" 300 meters away and so many 33 meters high. would O'Malley's kick have cleared this goal post?
