*46. Go Stones are thrown horizontally with the same velocity from the tops of two different buildings. One stone lands twice as far from the base of the building from which it was thrown as does the other stone. Find the ratio of the height of the taller building to the height of the shorter building.

A football kicker is attempting a field goal from 39 m out. The ball is kicked and just clears thelower bar with a time of flight of 2.6 s. If the angle of the kick was 45°, what was the initial speed ofthe ball?A) 21.2 m/s B) 11.9 m/s C) 30.9 m/s D) 2.2 m/s
Immediately after the bouncing golf ball leaves the floor, its components of velocity are ?? = 0.662 ?/? and ?? = 3.66 ?/?. Determine the horizontal distance from the point where the ball left the floor to the point where it hit the floor again.
The record distance in the sport of throwing cowpats is 81.1 m.m. This record toss was set by Steve Urner of the United States in 1981 . Assuming the initial launch angle was 45∘45∘ and neglecting air resistance, determine (a) the initial speed of the projectile and (b) the total time the projectile was in flight.
Prove that the trajectory of a projectile is parabolic, having the form y=ax+bx2. To obtain this expression, solve the equation x=v0xt for t and substitute it into the expression for y=v0yt(1/2)gt2 (These equations describe the x and y positions of a projectile that starts at the origin.) You should obtain an equation of the form y=ax+bx2 where a and b are constants.
One of the fastest recorded pitches in major league baseball, thrown by Tim Lincecum in 2009, was clocked at 101.0 mi/h (Fig. P3.8). If a pitch were thrown horizontally with this velocity, how far would the ball fall vertically by the time it reached home plate, 60.5 ft away? Figure P3.8 Tim Lincecum throws a baseball.

A projectile is launched from ground level to the top of a cliff which is 195 m away and 155 m high. If the projectile lands on top of the cliff 7.6 s later it is fired, find the magnitude and direction of the initial velocity of the projectile.
A regulation volleyball court measures L = 18.0 meters in length and d = 2.43 meters in height. A volleyball player hits the ball from a height of h = 1.50 m just over the backline, and the initial velocity of the ball creates an angle of q = 30° with the ground. At what initial speed must the ball be struck such that it barely clears the net?
Eddie Manalak is a Filipino stuntman, he wishes to cross the 520m distance between two tall buildings by being shot from a cannon. He wishes to be launched at 60° to the horizontal so that he can spend more time in waving to the crowd. With what speed must he be launched? ANS. 76.7 m/s
A young man throws a ball horizontally from the roof of a 40 m high building. If the initial velocity with which the ball was thrown is Vo, determine how long does it take for the ball to hit the ground? A. 2.04 s b. 3.33 s c. 3.15 s d. 2.86 s
A marble is launched from the edge of a table at a angle of 45 ° up from horizontal and goes through the air until it hits the floor. True or False? For such a marble, |vx| (the magnitude of the x-component of the velocity) is decreasing the entire time the marble is airborne.
"Which is an accurate statement for general projectile motion, when the projectile is at the highest point of its trajectory?" Its acceleration is zero. Its velocity is perpendicular to the acceleration. Its velocity and acceleration are both zero. The horizontal component of its velocity is zero.
