6. You throw a ball out of a window at 4 m/s at a downward 30° angle. As a result, it takes 1.5 seconds for the ball to hit the ground. 30 A. How far does this ball travel horizontally before hitting the ground? (5.2 m) B. How high is this window from the ground? C. What is the velocity of this ball just before it hits the ground? Report your answer using components, or calculate the magnitude and direction.
2. A man throws a stone upward at an angle of 30 with the horizontal. It lands 60 m measured horizontally and 2 m below his arm measured vertically Determine the time of flight and the initial velocity of the stone. 3. Calculate the maximum horizontal distance, x a stone can be thrown, if its initial velocity is 18 m/s.

Question 9: A stone is thrown off of a bridge that is 40m above the water. The stone lands 48m from the base of the bridge. The stone was thrown with an initial velocity of 15m/s at 30 degrees above the horizontal. a) What are the initial position coordinates of the stone? b) What are the components of the initial velocity? (Answer: 13m/s, 7.5m/s) c) What is the maximum height the stone reaches above the water? (Answer:...
Student Id # Question A stone thrown off a bridge 20 m above a river has an initial velocity 5 m/sec of at an angle of 30 degrees above the horizontal as shown in the figure. Find the location (x.y) of the stone after 1 second? What is the velocity (V1, and V1,) after 1 second? It will take T seconds to hit the water, what is T? What is the velocity (V2, and V2,) when it hits the water?...
(1) (1 point) Write the vector form of velocity a function of
v0, θ, t for when the projectile is in flight (before it hits the
ground).
(2) (1 point) Write the down horizontal and vertical
displacements as a function of t, v0, θ.
(3) (1 point) Give the expression for time of flight as a
function of v0, θ, φ. (Hint: use previous results and tan(φ) =
y/x)
(4) (1 point) Give the expression for distance travelled along
the...
You throw your phone straight out horizontally so that is leaves your hand with a velocity of 15.6 m/s forward. When the phone leaves your hand, its vertical height is 1 m above the ground. Once it leaves your hand, it begins to fall while moving forward due to gravity pulling it downward. a. What is the phones initial velocity in the horizontal (forward) direction in the instant it leaves your hand? b. What is the phones initial velocity in...
While standing on a bridge 30.0 m above the ground, you drop a stone from rest. When the stone has fallen 5.00 m, you throw a second stone straight down. What initial velocity must you give the second stone if they are both to reach the ground at the same instant? Take the downward direction to be the negative direction.
Two boys are throwing stones off of a 120 meter cliff to see who can throw the furthest. Both can throw a stone with the same initial velocity of 12 m/s. Boy A launches the stone with an initial angle of 30 degrees, and Boy B throws with initial angle of 60 degrees. A.) Draw a sketch of the trajectory of both of the stones on a single plot. B.) Calculate the components of the initial velocity. C.) Calculate the...
